backends/native: Fix cursor renderer assignment for tablet devices

Browse Source 
We create a cursor renderer per device for those at
meta_seat_native_handle_event_post() with PROXIMITY_IN events, but
the MetaWaylandTabletTool handles the event before that, and goes
with a NULL cursor renderer.

Make MetaBackend::get_cursor_renderer() on the native backend create
those cursor renderers on demand, and only handle PROXIMITY_OUT in
handle_event_post() to dispose those. This makes MetaWaylandTabletTool
happily get a cursor renderer again.
