desktop/output: Stop repaint loop when not needed

Browse source 
1e0031781f refactored repaint to accumulate all changes in a single
wlr_output_state and commit them at the end of the repaint loop,
replacing a call to wlr_scene_output_commit. wlr_scene_output_commit
contains an early bail-out when no frame has been requested and no
damage has accumulated, which was not replicated as part of this
refactor, causing the repaint loop to never pause.

Replicate the logic to stop the repaint loop as needed.

Fixes: 1e0031781f ("desktop/output: unify page-flip codepath")
