Star Zeng 353f5ba92f IntelFrameworkModulePkg AcpiS3SaveDxe: Reduce reserved memory consumption
Reduce reserved memory consumption by page table buffer,
then OS can have more available memory to use.
Take PhysicalAddressBits = 48 and 2MB page granularity as example,
1:1 Virtual to Physical identity mapping page table buffer needs to be
((512 + 1) * 512 + 1) * 4096 = 1075843072 bytes = 0x40201000 bytes.

When BIOS does not support long mode waking vector, only allocate
2 pages (1G page enabled) or 6 pages for 4G page table, and 8 extra
pages to handles > 4G request by page fault.
