vc/intel/FSP2_0/CPX-SP: add FSPM DIMM watermark option

FSPM MemRefreshWatermark option support is present in FB's CPX-SP
FSP binary, but not in Intel's CPX-SP FSP binary.

In CPX-SP soc code, add a Kconfig HAVE_FSPM_DIMM_WATERMARK_OPTION to
indicate whether the FSP binary supports such option.

For DeltaLake mainboard, when such option is set, if corresponding
VPD variable is set, use it to control the behavior.
