The TOCTOU vulnerability allow that the physical present person to replace the code with the normal BootGuard check and PCR0 value.
The issue occur when BootGuard measure IBB and access flash code after NEM disable.
the reason why we access the flash code is that we have some pointer to flash.
To avoid this vulnerability, we need to convert those pointers, the patch series do this work and make sure that no code will access flash address.

v2:
Create gEdkiiMigratedFvInfoGuid HOB and add PcdMigrateTemporaryRamFirmwareVolumes to control whole feature.

v3:
Remove changes which is not related with the feature and disable the feature in virtual platform.

v4:
Disable the feature as default, Copy the Tcg2Pei behavior to TcgPei
