Implement a VideoToolbox H265 decoder in WebCore
rdar://187770610
https://bugs.webkit.org/show_bug.cgi?id=324534
Reviewed by Jean-Yves Avenard.
We implement GPUVideoDecoderVTBH265 as a straigthforward replacement to
libwebrtc RTCVideoDecoderH265.
At some point in the future, RTCVideoDecoderH265 will be retired.
In the meantime, we enable GPUVideoDecoderVTBH265 when WebCore's H265 encoder
is enabled.
We reimplement libwebrtc parsing/conversion routines that are needed in
WebCore, using safe cpp guideline.
We keep for now the color space handling similar to libwebrtc (fixed setup),
this will be fixed as a follow-up.
