refactor: Update animation frame handling in artplayer-proxy-webav

The code changes replace the use of `requestAnimationFrame` with `setInterval` in the `start` function of `artplayer-proxy-webav`. This change improves the performance and stability of the animation frame handling, ensuring a smoother playback experience.
