IntelFsp2Pkg: Support to return error status from FSP API done

Added FspMemoryInitDone2, FspTempRamExitDone2, FspSiliconInitDone2
to return error status to Boot Loader for FSP API calls.
To maintain backward compatibility existing functions
(FspMemoryInitDone, FspTempRamExitDone, FspSiliconInitDone)
declaration left untouched.
