    [GStreamer] Misc leak fixes
    https://bugs.webkit.org/show_bug.cgi?id=266188

    Reviewed by Xabier Rodriguez-Calvar.

    The GStreamer device-related objects were leaked, along with a couple GstStream objects in the
    player. There are more issues, specially in the MSE code, but that's for another time...

    We now explicitely clean-up the capture device managers and the registry scanner before
    de-initializing GStreamer. The FastMalloc allocator is flagged as leaked as well, as it is static
    and I didn't find how to properly clean it up.
