output: introduce wlr_output_schedule_done
This commit introduces wlr_output_schedule_done and refactors the mechanism used to send wl_output events to clients. wlr_output_schedule_done schedules a wl_output.done event. This allows clients to see wlr_output property changes as atomic. This function is also useful for add-on interfaces like xdg_output which need to trigger a wl_output.done event to apply their new state.
