Hao Wu a10acf0e20 MdeModulePkg/Core: Refine handling NULL detection in NX setting
The commit rewrites the logic in function
InitializeDxeNxMemoryProtectionPolicy() for handling the first page
(page 0) when NULL pointer detection feature is enabled.

Instead of skip setting the page 0, the codes will now override the
attribute setting of page 0 by adding the 'EFI_MEMORY_RP' attribute.

The purpose is to make it easy for other special handling of pages
(e.g. the first page of the stack when stack guard feature is enabled).
