/**
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 _gDriverUnloadImageCount is greater than zero, then an unload
handler must be registered for this image
and the unload handler must invoke ProcessModuleUnloadList().
If _gUefiDriverRevision is not zero and SystemTable->Hdr.Revision is less
than _gUefiDriverRevison, then return EFI_INCOMPATIBLE_VERSION.
@param ImageHandle The image handle of the Standalone MM Driver.
@param SystemTable A pointer to the EFI System Table.
@retval EFI_SUCCESS The Standalone MM Driver exited normally.
@retval EFI_INCOMPATIBLE_VERSION _gUefiDriverRevision is greater than
SystemTable->Hdr.Revision.
@retval Other Return value from ProcessModuleEntryPointList().
