BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275
The VMM launch sequence should have pre-validated all the data pages used
in the Reset vector. The range does not cover the data pages used during
the SEC phase (mainly PEI and DXE firmware volume decompression memory).
When SEV-SNP is active, the memory must be pre-validated before the access.
Add support to pre-validate the memory range from SnpSecPreValidatedStart
to SnpSecPreValidatedEnd. This should be sufficent to enter into the PEI
phase.

Leif suggested that FDF include files should preferably refer with their
names to the FDF file sections from which they are included.
Therefore
- rename "OvmfPkg.fdf.inc" to "OvmfPkgDefines.fdf.inc" (included from the
[Defines] section),
- rename "DecomprScratchEnd.fdf.inc" to "FvmainCompactScratchEnd.fdf.inc"
(included under the [FV.FVMAIN_COMPACT] section).
