Fix a conformance issue in gBS->CreateEvent() & gBS->CreateEventEx(): 

1. gBS->CreateEventEx() with EventGroup = NULL should behavior like gBS->CreateEvent()
2. EVT_SIGNAL_EXIT_BOOT_SERVICES & EVT_SIGNAL_VIRTUAL_ADDRESS_CHANGE are invalid parameters for gBS->CreateEventEx() if the EventGroup is not NULL.
