Revert "Add option to call VMAF in compare_videos.py."
This reverts commit e307d56bd7e192c354871a739bc0133d88cb5379.
Reason for revert:
Breaks client.webrtc.perf bots. Example failure:

AttributeError: Values instance has no attribute 'yuv_directory'
Original change's description:
> Add option to call VMAF in compare_videos.py.
>
> VMAF compares videos on several metrics and produces a unified score.
>
> Calling it from compare_videos required passing in a path to a VMAF
> directory, where there should be a C++ wrapper executable and a model.
> For now, the relative paths to those are constant.
>
> VMAF needs to compare aligned videos in YUV format, so two videos
> (ref and test) will be saved by frame_analyzer after it has aligned
> them.
>
> Bug: webrtc:9642
