Jordan Justen 7cb6b0e068 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.

jljusten 0913fadc1a OVMF SEC: Modify to match new interface of reset vector module
Previously the interface to the SEC module was:
  ESI/RSI - SEC Core entry point
  EDI/RDI - PEI Core entry point
  EBP/RBP - Start of BFV

Now it is:
  RAX/EAX  Initial value of the EAX register
           (BIST: Built-in Self Test)
  DI       'BP': boot-strap processor, or
           'AP': application processor
  RBP/EBP  Address of Boot Firmware Volume (BFV)
