Make sure natural_size is set when a frame is cropped.
If the natural size is not set, the <video> tag will set its properties videoHeight and videoWidth to the original, uncropped width and height.If that is used for deciding the <video> render size- the aspect ratio will be wrong.

This cl allow setting the natural_size as well as the visible_rect when calling media::VideoFrame::WrapVideoFrame.
