For some media, the container's |natural_size| is actually just an
aspect ratio, and therefore we should not use it directly as the
VideoFrame's |natural_size|. Instead it should be scaled based on the
|visible_rect| of the decoded frame.

FFmpegVideoDecoder already does this, this CL applies the same logic in
GpuVideoDecoder and VdaVideoDecoder.

Note: This change will make it possible for HW decoders to emit frames
of different sizes without a config change, which was not possible
before.
