Overhaul resize presentation and wallpaper rendering

Coordinate native-pixel resize handoffs, fractional geometry and shared animation timing. Delegate wallpaper rendering to the compositor, advertise DMA-BUF device feedback, and improve callback pacing and render metrics.

Handle monitor-local shell surfaces, lid-driven output evacuation and workspace restoration.
