Original issue's description:
> H264 HW encode using VideoToolbox
>
> This CL adds VTVideoEncodeAccelerator which enables H264 encode support using
> VideoToolbox on mac. Also, it includes a refactor of common VideoToolbox classes
> under video_toolbox_helpers.*.
>
> Note that, this is the first CL and H264 codec is still behind a flag. More
> patches will follow adding additional codec profiles and support for
> bitrate adaptations.
