[win32] Use deviceZoom in single zoom mapper

This commit replaces the usage of the zoom attribute in methods in the
SingleZoomCoordinateMapper that translate Point and Rectangle from and
to display coordinates to use DPIUtil.getDeviceZoom() instead. The
implementation was not consistent yet, as e.g. in
SingleZoomCoordinateMapper#getCursorLocation or
SingleZoomCoordinateMapper#setCursorLocation DPIUtil.getDeviceZoom() is
already used.
