IntelFsp2Pkg: Add FSP*_ARCH_UPD. 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2781

Introduce FSPT_ARCH_UPD and FSPS_ARCH_UPD to support debug events
and multi-phase silicon initialization.
For backward compatibility the original structures are kept and
new ARCH_UPD structures will be included only when UPD header
revision equal or greater than 2.

GenCfgOpt script also updated to prevent from generating duplicate
FSPT_ARCH_UPD and FSPS_ARCH_UPD typedef structures.
