Implement WebCodecsVideoEncoder with VPx backend

https://bugs.webkit.org/show_bug.cgi?id=245954
rdar://problem/100708947

Introduce VideoEncoder interface that is used by WebCodecsVideoEncoder as the interface to actual encoders.
Implement WebCodecs VideoEncoder algorithms.
Add VP8 and VP9 decoder implementations for VideoEncoder using libvpx.
