From: Michael Kubacki <michael.kuba...@microsoft.com> REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3218
Adds an INF for StandaloneMmCpuFeaturesLib, which supports building the SmmCpuFeaturesLib code for Standalone MM. Minimal code changes are made to allow reuse of existing code for Standalone MM. The original INF file names are left intact (continue to use SMM terminology) to retain backward compatibility with platforms that use those INFs. Similarly, the pre-existing C file names are unchanged to be consistent with the INF file names. Note that all references in library source files to PiSmm.h have been changed to PiMm.h for consistency.
