[PATCH] BaseTools/GenFv: Support SecCore and PeiCore in different FV

["Chasel, Chiu" <chasel.chiu@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1423

There is usage model that SecCore and PeiCore are in different FVs.
Update BaseTools to support this usage model.

Test: Verified on internal platform with the case SecCore and
PeiCore in different FVs and built/booted successfully.
