> Reorganize media::VideoCapture* types
> 
> The purpose of this CL is to clean up the distinction between
> VideoCaptureFormat (which identifies the captured type of a frame),
> VideoCaptureParams (which identifies the requested format of a capture),
> and VideoCaptureCapability (which identifies the capture capabilities of a
> device).
> 
> Notably:
> * VideoCaptureFormat::frame_size_type ->
>   VideoCaptureParams::allow_resolution_change, as variable resolution
>   capability is a per-session, not a per-frame property.
> * VideoCaptureCapability::color -> VideoCaptureFormat::pixel_format, as frame
>   color format is a per-frame property.
>   * As VideoCaptureParams holds a VideoCaptureFormat member, capture requests
>     are able now to request a particular capture color format.
