From: Pierre Gondois <pierre.gond...@arm.com>

To enable CI support of the tianocore/edk2-platforms repository,
add YML configuration files used to run Continuous Integration (CI)
checks on Azure Pipelines agents.

These files are copies of the files from the tianocore/edk2
repository. Any modification to the tianocore/edk2 files must be
reflected on the tianocore/edk2-platforms copies.

The following files have been modified:
 - .azurepipelines/templates/platform-build-run-steps.yml
 - .azurepipelines/templates/pr-gate-build-job.yml
 - .azurepipelines/templates/pr-gate-steps.yml

The sections modified are marked with the following comments:
 -EDK2_PLATFORMS_MODIF_START
 -EDK2_PLATFORMS_MODIF_END

Notes:
    v3:
     - Align with the latest version in the edk2 repository. [Sean]
     - Replace Readme(s)'s content with a reference to the
       edk2 repository. [Sean]
     - Add step to checkout edk2's latest master in the CI. [Pierre]
    v4:
     - Checkout edk2 repository in Ubuntu-PatchCheck.yml to
       get the PatchCheck.py script. [Pierre]
