Build SMM HOBs for universal payload

Browse Source 
UEFI payload built from open sourced EDK2 supports SMM variable now.
So build the required HOBs to work with EDK2.
This patch just changed the common SBL code, so there is no platform
change required.
This patch also added a PCD PcdBuildSmmHobs for old SMM HOBs and new
SMM HOBs. Late old SMM HOBs might be dropped.
