splitmuxsink: Add fragment offset and duration to message
Publish the playback offset for and duration into the splitmuxsink-fragment-closed bus message as each fragment finishes. These can be passed to splitmuxsrc via the 'add-fragment' signal to avoid splitmuxsrc measuring all files on startup Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7053>
