QQuickWindow track changes via DevicePixelRatioChange event
Qt core gained a new event on the window when the dpr changes.
This is important as the window DPR can differ from the screen device
pixel ratio, it also allows us to get rid of one level of the screen
connection tracking.
Fixes: QTBUG-113236
