[PATCH v4] IntelFsp2Pkg: Add FSPI_ARCH_UPD.

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

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3993

Adding the missing FSPI_ARCH_UPD, FSP_GLOBAL_DATA_VERSION bumpping up,
and some comments for clarification.
Also fixed a bug in SplitFspBin.py for FSP-I support.
