Rob Bradford cf735b54df wayland: Add accessor API to permit access to underlying Wayland structures 
* clutter_wayland_input_device_get_wl_input_device for the input device
* clutter_wayland_stage_get_wl_surface for the Wayland surface
* clutter_wayland_stage_get_wl_shell_surface for the shell surface
