MdeModulePkg/PeiMain: Support EFI_PEI_CORE_FV_LOCATION_PPI
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1524
When shadowing PeiCore the EFI_PEI_CORE_FV_LOCATION_PPI
should be checked to see if PeiCore not in BFV, otherwise
just shadowing PeiCore from BFV.
Test: Verified on internal platform and booting successfully.
