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. In MdeModulePkg, PeiCore installs mMigrateTempRamPpi if PcdMigrateTemporaryRamFirmwareVolumes is True before NEM tear down and after permanent memory ready.
