Update the Mem Map and MAT Shell Test to Support RUNTIME_PAGE_ALLOCATION_GRANULARITY Alignment

[os-d]

Description

The Mem Map and MAT shell test currently has a hard dependency on 4k alignment of EFI_MEMORY_MAP and MAT table entries. This is only valid when the RUNTIME_PAGE_ALLOCATION_GRANULARITY is 4k. To make this more universal, compare the MAT entries to RUNTIME_PAGE_ALLOCATION_GRANULARITY as well as the UEFI spec defined EFI_MEMORY_MAP types that should have RUNTIME_PAGE_ALLOCATION_GRANULARITY.

As a small cleanup, rename LegacyMemoryMap to EfiMemoryMap as it is certainly not legacy and to avoid confusion :).

This also removes a duplicate test.

For each item, place an "x" in between [ and ] if true. Example: [x].

How This Was Tested

Tested by running the shell app on Q35 and confirming it still succeeds.

Integration Instructions

N/A. This has no dependency on mu_basecore 64k changes because the RUNTIME_PAGE_ALLOCATION_GRANULARITY is what we expect the MAT and runtime EFI_MEMORY_MAP entries to be aligned to, regardless of whether that is 4k or 64k.
