UefiCpuPkg: PiSmmCpuDxeSmm: Remove Framework compatibility
The PiSmmCpuDxeSmm module is using PcdFrameworkCompatibilitySupport to
provide compatibility with the SMM support in the IntelFrameworkPkg.
This change removes the Framework compatibility and requires all SMM
modules that provide SMI handlers to follow the PI Specification.
