Add accessors for QWindow and QScreen to QWidgetPrivate

Rewrite the existing accessor QWidgetPrivate::windowHandle() to
accept a mode enumeration that has an "Any" convenience.

Based on that, add QWidgetPrivate::associatedScreen(), which is seful
in many places where scaling is performed.

Prototypically simplify the code.
