UefiCpuPkg/SmmCpuFeaturesLib: Add Standalone MM support for AMD family

Add the INF file of AmdStandaloneMmCpuFeaturesLib for AMD family, which
supports building the SmmCpuFeaturesLib code for Standalone MM. It is
based on the existing file, StandaloneMmCpuFeaturesLib.inf. Minimal code
changes are also made to allow reuse of existing code for Standalone MM.
