When taking the scanout path we still want to clear the redraw-clip from the stage-view in order to ensure we skip frames in `handle_frame_clock_frame()` if no new redraw-clip was recorded. This was not done previously as the accumulated redraw-clip was needed for the next repaint, likely under the assumption that scheduling a scanout repeatedly would be computationally cost-free. This assumption does not hold in a VRR world. In order to archive both, an accumulated redraw-clip for the next paint and frame-skipping during scanout, introduce new API to defer and accumulate redraw-clips until the next repaint.
