Cheng Sun 1065536c64 MdeModulePkg: Support customized FV Migration Information
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4533

There are use cases which not all FVs need be migrated from TempRam to
permanent memory before TempRam tears down. This new guid is introduced
to avoid unnecessary FV migration to improve boot performance. Platform
can publish MigrationInfo hob with this guid to customize FV migration
info, and PeiCore will only migrate FVs indicated by this Hob info.

This is a backwards compatible change, PeiCore will check MigrationInfo
hob before migration. If MigrationInfo hobs exists, only migrate FVs
recorded by hobs. If MigrationInfo hobs not exists, migrate all FVs to
permanent memory.

Guomin Jiang 4b68cef04c MdeModulePkg/Core: Create Migrated FV Info Hob for calculating hash (CVE-2019-11098)
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1614

When we allocate pool to save the rebased PEIMs, the address will change
randomly, therefore the hash will change and result PCR0 change as well.
To avoid this, we save the raw PEIMs and use it to calculate hash.

The MigratedFvInfo HOB will never produce when
PcdMigrateTemporaryRamFirmwareVolumes is FALSE, because the PCD control
the total feature.
