Calculate the frame deadline in ClutterFrameClock's calculate_next_update_time_us() rather than in MetaWaylandCompositor's on_after_update(). The specifics of the deadline calculation for a given frame should be implementation detail of the frame clock and and remain internal to allow extensibility. This extensibility is specifically useful for scenarios where a different deadline calculation is needed due to alternative frame scheduling logic, such as for VRR. No change in behavior.
