Store the video info of the internal frame decode width/height separate to the exposed (cropped) frame info, so that it can be used for mapping the downstream allocated video frame buffer correctly when using GstVideoCropMeta. Fixes playback of files with sizes that aren't a multiple of 16-pixels width or height. https://bugzilla.gnome.org/show_bug.cgi?id=741030
