BaseTools: Fix the issue caused by tostring() removal on Py39

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()

-===========================
-
-To build the BaseTools, you should run the standard vsvars32.bat script
-from your preferred Visual Studio installation or you can run get_vsvars.bat
-to use latest automatically detected version.
-
-In addition to this, you should set the following environment variables::
-
- * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree
- * BASE_TOOLS_PATH - The directory where the BaseTools source is located.
-   (It is the same directory where this README.rst is located.)
-
-After this, you can run the toolsetup.bat file, which is in the same
-directory as this file.  It should setup the remainder of the environment,
-and build the tools if necessary.
-
-Please also refer to the ``BuildNotes.txt`` file for more information on
-building under Windows.
-
-Unix-like operating systems
-===========================
-
-To build on Unix-like operating systems, you only need to type ``make`` in
-the base directory of the project.
-
-Ubuntu Notes
-============
-
-On Ubuntu, the following command should install all the necessary build
-packages to build all the C BaseTools::
-
- sudo apt install build-essential uuid-dev

+Please copy it manually from <PythonHome>\DLLs.

-  @{
-    @par Summary
-    @{
-    ACPI tables are categorized as data tables and definition block
-    tables. Dynamic Tables Framework currently supports generation of ACPI
-    data tables. Generation of definition block tables is difficult as these
-    tables are encoded in ACPI Machine Language (AML), which has a complex
-    grammar.
-
-    Dynamic AML Generation is an extension to the Dynamic tables Framework.
-    One of the techniques used to simplify definition block generation is to
-    fixup a template SSDT table.
-
-    Dynamic AML aims to provide a framework that allows fixing up of an ACPI
-    SSDT template with appropriate information about the hardware.
-
-    This framework consists of an:
-    - AMLLib core that implements a rich set of interfaces to parse, traverse
-      and update AML data.
-    - AMLLib library APIs that provides interfaces to search and updates nodes
-      in the AML namespace.
