Add a signal that allows adding fragments with a specific offset and duration directly to splitmuxsrc's list. By providing the fragment's offset on the playback timeline and duration directly, splitmuxsrc doesn't need to measure the fragment making for faster startup times. Add a bus message that's published when fragments are measured, reporting the offset and duration, so they can be cached by an application and used on future invocations. Add examples for handling the bus message and using the 'add-fragment' signal. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7053>
