IntelSiliconPkg/Feature/SmmControl: Implement PPI with chipset support

S3 resume may require communication with SMM, for which we need the
SmmControl PPI. Therefore, port the DXE drivers to a library, like there
is for SMM Access.

Tested, working on Kabylake. Further testing required after the refactor
for compatibility.
