Allows for reference counting of images before disposal. This will allow multiple callers to hold a reference to an image and dispose of their reference without disposing the underlying image until all handles have been disposed. This will be used by the framework to help resolve some of the kludge I was trying to introduce in flutter/flutter#64582
