winrt: Fix display of tooltips

This touches multiple areas. First adding a tooltip to the window list
should not automatically invoke focussing and hence
handleWindowActivated should not be invoked. This is the same approach
as on the windows qpa.

The winrt qpa supports multiple (non-fullscreen) windows since a while.
However, pointerUpdated still acted on the top level window, which
caused problems resolving the real target of a mouse event. In this case
the tooltip received all events, while the application window should get
them. Hence identify the target window via the system coordinates.
