winrt: mouse handling: Fix detection of affected window

With the previous implementation the detection of the
affected window (windowAt which uses QWindow::geometry)
only worked for the upper left quarter of the window,
when used on a High DPI screen. As QWindow does not use
native positions, the mouse cursor's position has to be
mapped before checking the window under the mouse.
