iOS: Move statusbar visibility handling to QIOSViewController

It doesn't belong in QIOScreen, and simplifies the flow when changing
the focus window or the window state of the focus window. Both will
result in calling updateProperties on the view-controller, which will
re-configure the statusbar visibility and hide/show it as appropriate,
before triggering a re-layout of its own view, which will in turn
trigger an update of the screen properties based on the new statusbar
state, before re-layouting of QWindow based on the new screen state.
