Bump xdg-shell version from 3 to 6

- Send xdg_toplevel.wm_capabilities
- Send xdg_toplevel.configure_bounds so that clients can map a window that
  fits within the usable area, without relying on
  view_constrain_size_to_that_of_usable_area() which is called after map.
- (The new "suspended" state should be handled by wlr_scene in the future)
