This patch series is the second version of
MdeModulePkg: DxeCore: Don't Guard Large Runtime Granularity Allocations​.
The subject line has been updated because this went from a one commit
patch with no cover letter to a multi-commit patch.

The commit messages cover the vast amount of detail here, but this
patchset fixes three issues:
- a UEFI spec violation for which memory types require runtime page
allocation granularity alignment
- An incompatibility of the heap guard system to guard these regions
that require runtime page allocation granularities greater than
the EFI_PAGE_SIZE.
- A CodeQL error that fails CI when updating the Page.c code

v2:
- Add commit to fix UEFI spec violation
- Add commit to fix newly flagged CodeQL error
- Update guard commit message, comments, and static assert to use
the correct types
