  The entry point of PE/COFF Image for a Standalone MM Driver.

  This function is the entry point for a Standalone MM Driver.
  This function must call ProcessLibraryConstructorList() and
  ProcessModuleEntryPointList().
  If the return status from ProcessModuleEntryPointList()
  is an error status, then ProcessLibraryDestructorList() must be called.
  The return value from ProcessModuleEntryPointList() is returned.
  If _gMmRevision is not zero and MmSystemTable->Hdr.Revision is
  less than _gMmRevision, then return EFI_INCOMPATIBLE_VERSION.

  @param  ImageHandle    The image handle of the Standalone MM Driver.
  @param  MmSystemTable  A pointer to the MM System Table.

  @retval  EFI_SUCCESS               The Standalone MM Driver exited normally.
  @retval  EFI_INCOMPATIBLE_VERSION  _gMmRevision is greater than
                                     MmSystemTable->Hdr.Revision.
