wayland: fix frame pacing regression, schedule frame after dispatch 

The extra wlr_scene_output_commit broke frame pacing in nested mode by
consuming the host frame callback. Instead, move wlr_output_schedule_frame
to after wl_event_loop_dispatch so client commits processed during
dispatch are rendered on the next frame event.
