[Feature]: Support host based unit test on ARM systems #495
Description
Feature Overview
Today's host based unit test is heavily based on x86 architecture. As more targets are for ARM/AARCH64 systems nowadays, there is more need for running host based unit tests on the same architecture as the targets for better test fidelity.
However, the current host based unit test framework mainly builds for x86 systems and would introduce build breaks if we want to compile host based unit tests for AARCH64. i.e. this structure does not exist on ARM systems: https://github.com/microsoft/mu_basecore/blob/3f022dad7ac0035cfe3ed49a12403a7314445383/MdePkg/Test/UnitTest/Include/Library/UnitTestHostBaseLib.h#L88C20-L88C20.
Solution Overview
Plum through the build break when building on host based unit on ARM system and start to deploy the existing host based unit tests to ARM builds (Windows and Linnux).
There might be further tuning for plugins to make the entire flow functional.
