MdeModulePkg: Support customized FV Migration Information

Browse Source 
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.
