  [GStreamer][WebCodecs] AV1 (with dav1d) decoding fixes
https://bugs.webkit.org/show_bug.cgi?id=272642

Reviewed by Xabier Rodriguez-Calvar.

The decoder tests were failing mostly due to incomplete colorimetry handling in dav1ddec, which was
fixed upstream. The low-latency decoding test was failing because we were not configuring the
decoder to internally use a single thread. The parser was discarding corrupted frames, leading to
another test failure, so it was removed from the harnessed pipeline (the decoder rejects corrupted
frames already).
