ListView: allow flicking to both directions

Previously flicking was restricted to the orientation of the ListView.

[ChangeLog][QtQuick][ListView] Made it possible to enable horizontal
flicking in a vertical ListView, and vice versa. The only thing apps
must do is to specify the desired flick direction and the content
width (vertical ListView) or content height (horizontal ListView),
which is not calculated by ListView.
