MdePkg/ProcessorBind: add defines for page allocation granularity

The UEFI spec differs between architectures in the minimum alignment
and granularity of page allocations that are visible to the OS as
EFI_MEMORY_RUNTIME regions.

So define macros that carry these values to the respective ProcessorBind.h
header files.
