Revert "Add scaling interface to VideoFrameBuffer"

This reverts commit c79f1d8cfb48c348692320b05fa31598ed7067ca.

Reason for revert: Breaks downstream project.

Original change's description:
> Add scaling interface to VideoFrameBuffer
>
> This can be overriden for kNative frame types to perform scaling efficiently.
>
> Default implementations for existing buffer types require actual
> buffer implementation, thus this CL also merges "video_frame"
> with "video_frame_I420" build targets.
>
