Michael Kubacki 3163f34a42 BaseTools/Plugin: Clarify code coverage failure message
HostBasedUnitTestRunner.py is a build plugin responsible for locating
and executing host-based unit tests.

Recently, commit 6bb00aa introduced support for the plugin to
generate code coverage reports via lcov and OpenCppCoverage.

The plugin has discovered unit tests by searching for executables
with "Test" in the name for a while. However, the test coverage
change makes assumptions about test presence when crafting the
OpenCppCoverage command that ultimately fails with an ambiguous error
message if no host-based unit tests are discovered (see "ERROR").

```
SECTION - Run Host based Unit Tests
SUBSECTION - Testing for architecture: X64
ERROR - UnitTest Coverage: Failed to generate cobertura format xml in
        single package.
PROGRESS - --->Test Success: Host Unit Test Compiler Plugin NOOPT
```

This change preempts that message with a check in the plugin to
determine if any host-based tests were discovered. If not, a message
is printed with more guidance about how the developer should proceed
to either (1) fix their tests so code coverage is generated as
expected or (2) prevent the error message.

New message:

```
SECTION - Run Host based Unit Tests
SUBSECTION - Testing for architecture: X64
WARNING - UnitTest Coverage:
  No unit tests discovered. Test coverage will not be generated.

  Prevent this message by:
  1. Adding host-based unit tests to this package
  2. Ensuring tests have the word "Test" in their name
  3. Disabling HostUnitTestCompilerPlugin in the package CI YAML file
PROGRESS - --->Test Success: Host Unit Test Compiler Plugin NOOPT
```

  Note: New build instructions are available. It is recommended to start with
  the new instructions if learning how to build edk2 and/or BaseTools for the
  first time. This page is retained for reference.

New instructions: `Build Instructions`_

This directory contains the EDK II build tools and template files.
Templates are located in the Conf directory, while the tools executables for
Microsoft Windows Operating Systems are located in the Bin\\Win32 directory, other
directory contains tools source.

Build step to generate the binary tools
---------------------------------------

Windows/Visual Studio Notes
===========================

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.

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
