Since we marked the FV at PcdOvmfPeiMemFvBase as ACPI NVS memory,
we can use it on S3 resume.
The FV at PcdOvmfDxeMemFvBase may have been overwritten by the OS,
but we do not use it's contents on S3 resume.

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

individual DXE modules uncompressed
SECFV uncompressed
OVMF.fd after:
Non-volatile data storage
FVMAIN_COMPACT uncompressed
FV FFS file LZMA compressed
PEIFV uncompressed

This allow you to search for an 'instance' of a section
within a series of FFS sections.
For example, we will split the MAINFV into a PEI and DXE
FV, and then compress those two FV's together within a
FFS FV file. The DXE FV will appear as the second section
of the file, and therefore we will search for it using
an Instance=1 value.

These are all internal functions that don't interface with
assembly code or other drivers. Therefore EFIAPI is not
required.

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.

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.

Now for X64 we use a VTF0 ResetVector which puts the page
tables in RAM. Therefore SEC no longer needs to do this.
This reverts commit r14494.

This is based on MdeModulePkg/Core/DxeIplPeim/X64/VirtualMemory.c.
Previously we would run using page tables built into the
firmware device.
If a flash memory is available, it is unsafe for the page
tables to be stored in memory since the processor may try
to write to the page table data structures.
Additionally, when KVM ROM support is enabled for the
firmware device, then PEI fails to boot when the page
tables are in the firmware device.

* Only SEC is uncompressed now
* 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

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
