Creates a new steams-selected message. The message is used to announce
that an array of streams has been selected. This is generally in response
to a #GST_EVENT_SELECT_STREAMS event, or when an element (such as decodebin3)
makes an initial selection of streams.
The message also contains the #GstStreamCollection to which the various streams
belong to.
Users of gst_message_new_streams_selected() can add the selected streams with
gst_message_streams_selected_add().
