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.
