The destroy callback in wlr_switch_impl has been removed. The function `wlr_switch_finish` has been introduced to clean up the resources owned by a wlr_switch. `wlr_input_device_destroy` no longer destroys the wlr_switch, attempting to destroy a wlr_switch will result in a no-op. The field `name` has been added to the wlr_switch_impl to be able to identify a given wlr_switch device.
