presentation: only send sync output on presented (#12255)

as protocol states there is two events. 'presented' or 'discarded'.

wp_presentation_feedback::sync_output
As presentation can be synchronized to only one output at a time, this event tells which output it was.
This event is only sent prior to the presented event.
