    [MSE][GStreamer] Avoid extra/circular refs between tracks/streams
    https://bugs.webkit.org/show_bug.cgi?id=273488

    Reviewed by Alicia Boya Garcia.

    1. Avoid adding the same stream to the hash map. Also keeping the active/valid tracks in the player.
    2. Avoid a hard reference in the source buffer when ready for more samples.
    3. Break the indirect circular reference between the stream and track through the pad.
