[GStreamer][WebCodecs] Improve support for h.264 frames reordering in decoder
https://bugs.webkit.org/show_bug.cgi?id=265335
Reviewed by Youenn Fablet and Xabier Rodriguez-Calvar.
The GStreamer video decoder flush logic was flawed, assuming a flush-start/stop cycle would be
sufficient, but in practice we need to send EOS and teardown the element to force drain of the
decoder.
