[Cocoa] Reenable WebCodecs VP9 hardware decoder for AS
rdar://121693406
https://bugs.webkit.org/show_bug.cgi?id=268298
Reviewed by Eric Carlson.
WebCodecs allows to create decoders without width and height.
In that case, for VP9, we retrieve this information from the input format that
is parsed.
We can also parse whether we should use video range or full range pixel formats.
We update the buffer pool accordingly.
Finally, we no longer remove the kCVImageBufferCGColorSpaceKey like is done for
the H264 decoder as it is necessary to correctly render decoded video frames in
canvas.
We instead set it to sRGB.
Covered by
imported/w3c/web-platform-tests/webcodecs/full-cycle-test.https.any.html?vp9_p0
for the full range/video range fix.
Covered by
imported/w3c/web-platform-tests/webcodecs/videoFrame-createImageBitmap.https.any.worker.html
for the creation of decoder without width and height,
and the right color space usage.
