UefiCpuPkg/SecCore: Support EFI_PEI_CORE_FV_LOCATION_PPI 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1524

EFI_PEI_CORE_FV_LOCATION_PPI may be passed by platform
when PeiCore not in BFV so SecCore has to search PeiCore
either from the FV location provided by
EFI_PEI_CORE_FV_LOCATION_PPI or from BFV.

Test: Verified on internal platform and booting successfully.
