IntelFsp2Pkg: Improvement of supporting null UPD pointer in FSP-T
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4114
1.Use xmm5 slot 1 and xmm6 slot 3 to save ucode status and UPD pointer
respectively in TempRamInitApi in IA32 FspSecCoreT.
2.Correct inappropriate description in the return value of
AsmGetFspInfoHeader.
3.Replace hardcoded offset value 0x1C with FSP_HEADER_IMGBASE_OFFSET in
FspHeler.nasm.
