iOS: only activate top-level windows 

From before we would activate all QWindows that the user
tapped on, or setVisible were called on. This is wrong
since a QWindow does not have to be a top-level window.
For a non-alien widget application this would mean that
we would send activation events for all widgets that the
user tapped on all the time.

With this patch we do some extra checking before we
tell a QWindow to activate.
