wayland: Set current tool surface to NULL on prox-out

Browse source 
If an application is maximised, clutter_stage_pick_and_update_device()
goes into the
        if ((flags & CLUTTER_DEVICE_UPDATE_IGNORE_CACHE) == 0)
condition and returns the current actor for the device. This means no
CLUTTER_LEAVE/ENTER events are generated and in turn means the focus is
never invalidated and updated.

This leads to tool->focus_surface always being NULL and all events are
discarded.

Notably, tool->current is set to the right surface but
that one never changes either so meta_wayland_tablet_tool_set_current_surface()
exits early too because surface == tool->current and we thus never call
meta_wayland_input_invalidate_focus().
