    [GStreamer][MediaStream] Cleanup of state-change handling
    https://bugs.webkit.org/show_bug.cgi?id=252400

    Reviewed by Xabier Rodriguez-Calvar.

    Process upward transitions first, then chain to parent class and finally downward transitions. We
    also now stop observing tracks when going to NULL state, to match the corresponding upward
    transition.

    [GStreamer][MediaStream] Behave as a bandwidth-limited source element
    https://bugs.webkit.org/show_bug.cgi?id=252397

    Reviewed by Xabier Rodriguez-Calvar.

    Similar approach was used for the MSE source element in 260082 at main. This allows urisourcebin to
    disable buffering logic that doesn't make much sense anyway for this kind of streaming scenario.
