winrt: use visible bounds the get the visual area

On Windows Phone / Windows 10 Mobile, there are the status bar
and sometimes a navigation bar, which are hiding the visible
window area. In the Windows Phone code paths, the area of the
status bar was tracked and the visual area was dynamically shrinked.

This patch enables that we use ApplicationView::visibleBounds() on
every target (except Windows 8.1) to get the visible area of the
application. Its change event is now also used as a resize trigger
for manual resizing through user.
