wayland: Find touch grab sequence in subsurfaces also

Browse Source 
With libdecor, window moving/resizing only works with
the pointer, not with touch.
The meta_wayland_pointer_can_grab_surface checks for subsurfaces,
but the meta_wayland_touch_find_grab_sequence does not.

Add a similar subsurface check to
meta_wayland_touch_find_grab_sequence.
