Move visual overlay background management to QQuickPopup

During the early days, there was only one visual overlay background
dimmer, so QQuickOverlay was the natural choice to manage it. It was
soon realized that multiple modal popups and drawers needed each their
own background dimming. Now the implementation becomes simpler when
each popup manages its own background dimming. This paves the road for
the upcoming changes making it possible to provide background dimming
without ApplicationWindow.
