Fix compilation on impish

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3136

Python 3.9 remove the array.array.tostring and
array.array.fromstring() function. This patch
is to use other method to replace tostring() and
fromstring()

-# Azure DevOps Pipelines
-
-These yml files are used to provide CI builds using the Azure DevOps Pipeline Service.
-Most of the CI leverages edk2-pytools to support cross platform building and execution.
-
-## Core CI
-
-Focused on building and testing all packages in Edk2 without an actual target platform.
-
-See `.pytools/ReadMe.py` for more details
-
-## Platform CI
-
-Focused on building a single target platform and confirming functionality on that platform.
-
-## Conventions
-
-* Files extension should be *.yml.  *.yaml is also supported but in Edk2 we use those for our package configuration.
-* Platform CI files should be in the `<PlatformPkg>/.azurepipelines` folder.
-* Core CI files are in the root folder.
-* Shared templates are in the `templates` folder.
-* Top level CI files should be named `<host os>-<tool_chain_tag>.yml`

-## Lessons Learned
-
-### Templates and parameters
-
-They are great but evil.  If they are used as part of determining the steps of a build they must resolve before the build starts.  They can not use variables set in a yml or determined as part of a matrix.  If they are used in a step then they can be bound late.
-
-### File matching patterns
-
-On Linux this can hang if there are too many files in the search list.
-
-### Templates and file splitting
-
-Suggestion is to do one big yaml file that does what you want for one of your targets.  Then do the second one and find the deltas.  From that you can start to figure out the right split of files, steps, jobs.
-
-### Conditional steps
-
-If you want the step to show up in the log but not run, use a step conditional. This is great when a platform doesn't currently support a feature but you want the builders to know that the features exists and maybe someday it will.
-
-If you want the step to not show up use a template step conditional wrapper.  Beware this will be evaluated early (at build start).  This can hide things not needed on a given OS for example.

-# CI Templates
-
-This folder contains azure pipeline yml templates for "Core" and "Platform" Continuous Integration and PR validation.
-
-## Common CI templates
-
-### basetools-build-steps.yml
-
-This template compiles the Edk2 basetools from source.  The steps in this template are
-conditional and will only run if variable `pkg_count` is greater than 0.
-
-It also has two conditional steps only used when the toolchain contains GCC. These two steps
-use `apt` to update the system packages and add those necessary for Edk2 builds.
-
-## Core CI templates
-
-### pr-gate-build-job.yml
-
-This templates contains the jobs and most importantly the matrix of which packages and
-targets to run for Core CI.
-
-### pr-gate-steps.yml
-
-This template is the main Core CI template.  It controls all the steps run and is responsible for most functionality of the Core CI process.  This template sets
-the `pkg_count` variable using the `stuart_pr_eval` tool when the
-build type is "pull request"
-
-### spell-check-prereq-steps.yml
-
-This template installs the node based tools used by the spell checker plugin. The steps
-in this template are conditional and will only run if variable `pkg_count` is greater than 0.
-
-## Platform CI templates
-
-### platform-build-run-steps.yml
-
-This template makes heavy use of pytools to build and run a platform in the Edk2 repo
-
-Also uses basetools-build-steps.yml to compile basetools
-
-#### Special Notes
-
-* For a build type of pull request it will conditionally build if the patches change files that impact the platform.
-  * uses `stuart_pr_eval` to determine impact
-* For manual builds or CI builds it will always build the platform
-* It compiles basetools from source
-* Will use `stuart_build --FlashOnly` to attempt to run the built image if the `Run` parameter is set.
-* See the parameters block for expected configuration options
-* Parameter `extra_install_step` allows the caller to insert extra steps.  This is useful if additional dependencies, tools, or other things need to be installed.  Here is an example of installing qemu on Windows.
-
-    ``` yaml
-    steps:
-    - template: ../../.azurepipelines/templates/build-run-steps.yml
-      parameters:
-        extra_install_step:
-        - powershell: choco install qemu; Write-Host "##vso[task.prependpath]c:\Program Files\qemu"
-          displayName: Install QEMU and Set QEMU on path # friendly name displayed in the UI
-          condition: and(gt(variables.pkg_count, 0), succeeded())
-    ```

-# UncrustifyCheck Plugin
-
-This CiBuildPlugin scans all the files in a given package and checks for coding standard compliance issues.
-
-This plugin is enabled by default. If a package would like to prevent the plugin from reporting errors, it can do
-so by enabling [`AuditOnly`](#auditonly) mode.
-
-This plugin requires the directory containing the Uncrustify executable that should be used for this plugin to
-be specified in an environment variable named `UNCRUSTIFY_CI_PATH`. This unique variable name is used to avoid confusion
-with other paths to Uncrustify which might not be the expected build for use by this plugin.
-
-By default, an Uncrustify configuration file named "uncrustify.cfg" located in the same directory as the plugin is
-used. The value can be overridden to a package-specific path with the `ConfigFilePath` configuration file option.
-
-* Uncrustify source code and documentation: https://github.com/uncrustify/uncrustify
-* Project Mu Uncrustify fork source code and documentation: https://dev.azure.com/projectmu/Uncrustify
-
-## Files Checked in a Package
-
-By default, this plugin will discover all files in the package with the following default paths:
-
-```python
-[
-# C source
-"*.c",
-"*.h"
-]
-```
-
-From this list of files, any files ignored by Git or residing in a Git submodule will be removed. If Git is not
-found, submodules are not found, or ignored files are not found no changes are made to the list of discovered files.
-
-To control the paths checked in a given package, review the configuration options described in this file.
-
-## Configuration
-
-The plugin can be configured with a few optional configuration options.
-
-``` yaml
-  "UncrustifyCheck": {
-      "AdditionalIncludePaths": [], # Additional paths to check formatting (wildcards supported).
-      "AuditOnly": False,           # Don't fail the build if there are errors.  Just log them.
-      "ConfigFilePath": "",         # Custom path to an Uncrustify config file.
-      "IgnoreFiles": [],            # A list of file patterns to ignore.
-      "IgnoreStandardPaths": [],    # Standard Plugin defined paths that should be ignored.
-      "OutputFileDiffs": True,      # Output chunks of formatting diffs in the test case log.
-                                    # This can significantly slow down the plugin on very large packages.
-      "SkipGitExclusions": False    # Don't exclude git ignored files and files in git submodules.
-  }
-```
-
-### `AdditionalIncludePaths`
-
-A package configuration file can specify any additional paths to be included with this option.
-
-At this time, it is recommended all files run against the plugin be written in the C or C++ language.
-
-### `AuditOnly`
-
-`Boolean` - Default is `False`.
-
-If `True`, run the test in an "audit only mode" which will log all errors but instead of failing the build, it will set
-the test as skipped. This allows visibility into the failures without breaking the build.
-
-### `ConfigFilePath`
-
-`String` - Default is `"uncrustify.cfg"`
-
-When specified in the config file, this is a package relative path to the Uncrustify configuration file.
-
-### `IgnoreFiles`
-
-This option supports .gitignore file and folder matching strings including wildcards.
-
-The files specified by this configuration option will not be processed by Uncrustify.
-
-### `IgnoreStandardPaths`
-
-This plugin by default will check the below standard paths. A package configuration file can specify any of these paths
-to be ignored.
-
-```python
-[
-# C source
-"*.c",
-"*.h"
-]
-```
-
-### `OutputFileDiffs`
-
-`Boolean` - Default is `True`.
-
-If `True`, output diffs of formatting changes into the test case log. This is helpful to exactly understand what changes
-need to be made to the source code in order to fix a coding standard compliance issue.
-
-Note that calculating the file diffs on a very large set of of results (e.g. >100 files) can significantly slow down
-plugin execution.
-
-### `SkipGitExclusions`
-
-`Boolean` - Default is `False`.
-
-By default, files in paths matched in a .gitignore file or a recognized git submodule are excluded. If this option
-is `True`, the plugin will not attempt to recognize these files and exclude them.
-
-## High-Level Plugin Operation
-
-This plugin generates two main sets of temporary files:
-
-  1. A working directory in the directory `Build/.pytool/Plugin/Uncrustify`
-  2. For each source file with formatting errors, a sibling file with the `.uncrustify_plugin` extension
-
-The working directory contains temporary files unique to operation of the plugin. All of these files are removed on
-exit of the plugin including successful or unsuccessful execution (such as a Python exception occurring). If for any
-reason, any files in the package exist prior to running the plugin with the `.uncrustify_plugin` extension, the plugin
-will inform the user to remove these files and exit before running Uncrustify. This is to ensure the accuracy of the
-results reported from each execution instance of the plugin.
-
-The plugin determines the list of relevant files to check with Uncrustify and then invokes Uncrustify with that file
-list. For any files not compliant to the configuration file provided, Uncrustify will generate a corresponding file
-with the `.uncrustify_plugin` extension. The plugin discovers all of these files. If any such files are present, this
-indicates a formatting issue was found and the test is marked failed (unless `AuditOnly` mode is enabled).
-
-The test case log will contain a report of which files failed to format properly, allowing the user to run Uncrustify
-against the file locally to fix the issue. If the `OutputFileDiffs` configuration option is set to `True`, the plugin
-will output diff chunks for all code formatting issues in the test case log.

-### Prerequisites
+### Prerequisets
 
 1. A supported toolchain (others might work but this is what is tested and validated)
    * Windows 10:
      * VS 2017 or VS 2019
      * Windows SDK (for rc)
      * Windows WDK (for capsules)
-   * Ubuntu 18.04 or Fedora
+   * Ubuntu 16.04
      * GCC5
    * Easy to add more but this is the current state
 2. Python 3.7.x or newer on path
 3. git on path
 4. Recommended to setup and activate a python virtual environment
-5. Install the requirements `pip install --upgrade -r pip-requirements.txt`

 ### Module Inclusion Test - DscCompleteCheck
 
-This scans all INF files from a package and confirms they are
-listed in the package level DSC file. The test considers it an error if any INF
-does not appear in the `Components` section of the package-level DSC (indicating
-that it would not be built if the package were built). This is critical because
-much of the CI infrastructure assumes that all modules will be listed in the DSC
-and compiled.
-
-This test will ignore INFs in the following cases:
-
-1. When `MODULE_TYPE` = `HOST_APPLICATION`
-2. When a Library instance **only** supports the `HOST_APPLICATION` environment

-This test scans all INF files from a package for those related to host
-based unit tests and confirms they are listed in the unit test DSC file for the package.
-The test considers it an error if any INF meeting the requirements does not appear
-in the `Components` section of the unit test DSC. This is critical because

+This test scans all available modules (via INF files) and compares them to the
+package-level DSC file for the package each module is contained within. The test
+considers it an error if any module does not appear in the `Components` section

-A test that compiles the dsc for host based unit test apps.
-On Windows this will also enable a build plugin to execute that will run the unit tests and verify the results.

-These tools will be invoked on any CI

-#### Including Host-Based Tests in the Package YAML
-
-For example, looking at the `MdeModulePkg.ci.yaml` config file, there are two
-config options that control HostBased test behavior:
-
-```json
-    ## options defined .pytool/Plugin/HostUnitTestCompilerPlugin
-    "HostUnitTestCompilerPlugin": {
-        "DscPath": "Test/MdeModulePkgHostTest.dsc"
-    },
-```
-
-This option tell the test builder to run. The test builder needs to know which
-modules in this package are host-based tests, so that DSC path is provided.
-
-#### Configuring the HostBased DSC
-
-The HostBased DSC for `MdeModulePkg` is located at
-`MdeModulePkg/Test/MdeModulePkgHostTest.dsc`.
-
-To add automated host-based unit test building to a new package, create a
-similar DSC. The new DSC should make sure to have the `NOOPT` BUILD_TARGET
-and should include the line:
-
-```
-!include UnitTestFrameworkPkg/UnitTestFrameworkPkgHost.dsc.inc

-All of the modules that are included in the `Components` section of this
-DSC should be of type HOST_APPLICATION.
