Get rid of image_info_ from WebPChunk struct.

Browse Source 
The image_info_ was used only in GetImageCanvasWidthHeight(). So, now
we infer it from data there.
This removal fixes a bug: earlier, 'image_info' wasn't initialized in
the WebPMuxCreate() flow, and so the canvas width/height were being
calculated to be zero.

Also, a related refactoring: Combine CreateImageInfo() and
CreateDataFromImageInfo() into a single function CreateFrameTileData().
