On S3 resume, we skip decompression of the PEI FV, and expect
to jump directly into it. For this to work, we need the OS to
leave the memory range untouched.

Once we support ACPI S3, then we can restore this to
being allocated as ACPI NVS memory.
At that time we should also have a way to disable
S3 support in QEMU. When we detect that S3 is
disabled in QEMU, then we can allocate this as regular
Boot Services Data memory.

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

* 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
* The final output size will be a multiple of 64kb
