  [GStreamer][WebCodecs] Improve VPx encoding accuracy
https://bugs.webkit.org/show_bug.cgi?id=266966

Reviewed by Xabier Rodriguez-Calvar.

The codec string passed to the encoder is now parsed and converted to an input/output caps pair to
be used by the internal encoder. VPx encoders are now more accurately handling colorspace
informations. As follow-up, a similar approach can be used for avc and av1 cases.
