Michael Kubacki c19d18136e MdeModulePkg/Core/Pei: Fix pointer size mismatch in EvacuateTempRam()
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3512

In 32-bit PEI, the local variable pointers MigratedFvHeader and
RawDataFvHeader in EvacuateTempRam() will be 32-bit in size. The
pointers are currently passed to PeiServicesAllocatePages() which
expects a 64-bit output buffer of type EFI_PHYSICAL_ADDRESS.

When PeiServicesAllocatePages() writes to the buffer, the data
can overflow.
