Install event filter for QWindow based decorations

Browse source 
Also with QWindow based decorations the event filter is needed to
properly react on mouse button release and mouse move. Those are not
passed through KDecoration unlike the button press.

The event filter is adjusted to handle both filters installed on QWidget
and QWindow while QWindow only gets to see a subset of the events.

This fixes mouse interaction in Aurorae.
