overlay: optimize cache at the GstVideoOverlayRectangle level.
We previously assumed that an overlay composition changed if the number of overlay rectangles in there actually changed, or that the rectangle was updated, and thus its seqnum was also updated. Now, we can cope with cases where the GstVideoOverlayComposition grew by one or a few more overlay rectangles, and the initial overlay rectangles are kept as is.
