pwm_tool: Notify the toolhead that the move_queue needs to be flushed

Call toolhead.note_kinematic_activity() on each pin update to ensure that those updates will be flushed properly. This fixes "Timer too close" errors on SET_PIN commands that are issued when the toolhead is idle. Signed-off-by: Kevin O'Connor <[email protected]>
