UefiCpuPkg: Move MigrateGdt from DiscoverMemory to TempRamDone. (CVE-2019-11098)
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1614
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3160
The GDT still in flash with commit 60b12e69fb1c8c7180fdda92f008248b9ec83db1
after TempRamDone
So move the action to TempRamDone event to avoid reading GDT from flash.
