output: trigger frame/present events on all commits on enabled output

Browse source 
Up until now, frame/present events were only triggered when the
user submitted a buffer. Change the wlr_output API so that these
events are triggered when any commit is applied on an enabled
output.

Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3708
