```
gpui: Update animated image timing to pause when inactive (#52685)

- only advance frames and request animation frames while the window is
active.
- Reset last_frame_time to None when inactive to avoid fast catch-up
after resuming focus
- This fixes an issue where if you would have a gif open and lose focus,
the app tries to speedup to catch up the elapsed time

Might Close #21563, I shall measure the performance, I originally only
intended the fix to fix the speed up issue as I faced it while working
on gifs.
