Subject: Stop polish-and-sync timer when the window is destroyed

The threaded render loop continues to run the polish-and-sync timer for
ever in case the QQuickWindow is destroyed while the timer is active.
Instead of pumping the timer events on the render thread for ever, the
timer has to be killed somewhere.
