Add 4:4:4 encoding to WebCodecs for VP9. Simplify VpxVideoEncoder.

This adds support for configurable subsampling to WebCodecs along
with a test for the new behavior.

Implementing support in VpxVideoEncoder required simplifying how
it handles frame conversions and allocations. One unnecessary
allocation is actually removed from all encoding profiles.

Both I444 (profile 1) and I444P10 (profile 3) encoding are added.
