Implement cache property for QQuickAnimatedImage
Some longer and larger .gifs can consume a lot of memory
if every decoded frame is cached. Just as the backing QMovie
provides the ability to not cache frame, so should AnimatedImage.
This also allows a workaround for some animated image types
that can contain loops that aren't handled correctly (QTBUG-24869)
to not leak memory.
