Zhihao:
If Fsp-T/M is not installed, are they still used in PEI boot? If they are
used, I agree they should be measured.
Thanks

Issue description:
1. PeiCore only migrates Fsp-M in dispatch mode and doesn't migrate Fsp-T and
Fsp-M in Api mode.
2. Fsp-T and Fsp-M will be measured in post-mem PEI and the measurement uses
original addresses.
RootCause:
PeiCore only migrates installed FVs and Fsp-T/M may not be installed.
D
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4716
Migrate FSP-T/M binary from temporary RAM to permanent RAM before NEM
tear down. Tcg module will use permanent address of FSP-T/M for
measurement.
1. PeiCore installs mMigrateTempRamPpi if
PcdMigrateTemporaryRamFirmwareVolumes is True
2. Fsp
