OvmfPkg: Move SEC/PEI Temporary RAM from 0x70000 to 0x810000
Note: The Temporary RAM memory size is being reduced from
64KB to 32KB. This still appears to be more than
adequate for OVMF's early PEI phase. We will be adding
another 32KB range of RAM just above this range for
use on S3 resume.
The range is declared as part of MEMFD, so it is easier
to identify the memory range.
We also now assign PCDs to the memory range.
The PCDs are used to set the initial SEC/PEI stack in
SEC's assembly code.
The PCDs are also used in the SEC C code to setup
the Temporary RAM PPI.
