scene: schedule an output frame on wl_surface.frame 

Some clients (e.g. mpv, Firefox) request a new wl_surface.frame
callback without damaging their surface. When this happens,
schedule a new output frame.

Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3350
(cherry picked from commit 812951f5bc47f502429406e49f4e24f377b7799b)
