  [Cocoa] Reenable WebCodecs VP9 hardware decoder for AS

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.
