Awiral Shrivastava 5b08df03f8 MdeModulePkg: Optimize PEI Core Migration Algorithm
REF : https://bugzilla.tianocore.org/show_bug.cgi?id=4750

Migrate the FV that doesn't contain the currently executing PEI Core
when permanent memory is initialized but PEI Core is still potentially
running from faster memory (Tepmorary RAM). This may reduce the time
required to migrate FVs to permanent memory. The FV containing PEI
Core is migrated after the PEI Core reentry when it is executed from
permanent memory.

This may or may not improve performance depending on the behavior of
temporary RAM and the actual performance changes must be measured with
the feature enabled and disabled.

This migration algorithm is only used for FVs specified in the
gEdkiiMigrationInfoGuid HOB and built with flag
FLAGS_FV_MIGRATE_BEFORE_PEI_CORE_REENTRY.
