vc/intel/FSP2_0/CPX-SP: update to ww34 release and add watermark option

Intel CPX-SP FSP ww34 release annotates default values for FSP-M UPD
variables.

FSPM MemRefreshWatermark option support is present in FB's CPX-SP
FSP binary, but not in Intel's CPX-SP FSP binary. In FB's CPX-SP
FSP binary, this option takes the space of UnusedUpdSpace0[0].

For DeltaLake mainboard, if corresponding VPD variable is set, use it
to control the behavior. Such control is effective when FB's CPX-SP
FSP binary is used.
