BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3324
The SEV-ES stacks currently share a page with the reset code and data.
Separate the SEV-ES stacks from the reset vector code and data to avoid
possible stack overflows from overwriting the code and/or data.
When SEV-ES is enabled, invoke the GetWakeupBuffer() routine a second time
to allocate a new area, below the reset vector and data.
Both the PEI and DXE versions of GetWakeupBuffer() are changed so that
when PcdSevEsIsEnabled is true, they will track the previous reset buffer
allocation in order to ensure that the new buffer allocation is below the
previous allocation. When PcdSevEsIsEnabled is false, the original logic
is followed.
