Make gst_vaapi_display_get_display_type() return the actual VA display type. Conversely, add a gst_vaapi_display_get_class_type() function to return the type of the GstVaapiDisplay instance. The former is used to identify the display server onto which the application is running, and the latter to identify the original object class.
