MdeModulePkg: SmmReportStatusCodeLib: ReportStatusCodeLib in StandaloneMm

This change added support of StandaloneMm for ReportStatusCodeLib. It
adds a new instance of ReportStatusCodeLib for MM_STANDALONE type, and
abstracts the references of gMmst and gSmst functionalities into separate
files in order to link in proper Service Table for SMM core/drivers.
