Hey Ard,
Once the Memory Attribute Protocol is made available, Windows will have
some expectations about its functionality. Can you run this test app
created by me and Jiewen to ensure it meets the Windows requirements?
Part of the test needed an AARCH64 implementation which I just added -
let me know if it doesn't work.
Thanks :)

- enable stack guard in ArmVirtPkg (which uses EFI_MEMORY_RP)
- incorporate optimization from other series [0] to avoid splitting
block entries unnecessarily
v3:
- fix ARM32 bug in attribute conversion
- add Liming's ack to patch #1
- include draft patch (NOT FOR MERGE) used to test the changes
v2:
- drop patch to bump exposed UEFI revision to v2.10
- add missing permitted return values to protocol definition
