Jordan Justen b36f701d4f OvmfPkg: Split MAINFV into a separate PEI and DXE FVs
By splitting the PEI and DXE phases into separate FVs,
we can only reserve the PEI FV for ACPI S3 support.
This should save about 7MB.

Unfortunately, this all has to happen in a single commit.

DEC:
* Remove PcdOvmfMemFv(Base|Size)
* Add PcdOvmfPeiMemFv(Base|Size)
* Add PcdOvmfDxeMemFv(Base|Size)

FDF:
* Add new PEIFV. Move PEI modules here.
* Remove MAINFV
* Add PEIFV and DXEFV into FVMAIN_COMPACT
   - They are added as 2 sections of a file, and compressed
     together so they should retain good compression
* PcdOvmf(Pei|Dxe)MemFv(Base|Size) are set

SEC:
* Find both the PEI and DXE FVs after decompression.
   - Copy them separately to their memory locations.

Platform PEI driver:
* Fv.c: Publish both FVs as appropriate
* MemDetect.c: PcdOvmfMemFv(Base|Size) =>
                PcdOvmfDxeMemFv(Base|Size)

OVMF.fd before:

  Non-volatile data storage
  FVMAIN_COMPACT                    uncompressed
    FV FFS file                     LZMA compressed
      MAINFV                        uncompressed
        individual PEI modules      uncompressed
        FV FFS file                 compressed with PI_NONE
          DXEFV                     uncompressed
            individual DXE modules  uncompressed
  SECFV                             uncompressed

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.

Jordan Justen b382ede386 OvmfPkg X64 ResetVector: Move page tables from 512KB to 8MB
To help consolidate OVMF fixed memory uses, we declare this
range in MEMFD and thereby move it to 8MB.

We also now declare the table range in the FDF to set
PCDs. This allows us to ASSERT that CR3 is set as expected
in OVMF SEC.

OvmfPkgIa32.fdf and OvmfPkgIa32X64.fdf are updated simply
for consistency.

* The MAIN FV with PEI & DXE can easily shrink and grow as needed
* The final output will now be OVMF.Fv rather than OVMF.fd
* The final output size will be a multiple of 64kb

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)
