Fix caching issue with always_redraw causing incorrect object placement

- When animations are cached and skipped, ensure proper final state interpolation
- Call scene.update_to_time(scene.duration) to set animations to their end state
- Update all mobjects after interpolation to reflect final animation values
- Ensures ValueTrackers and always_redraw functions have correct values on cached renders
- Fixes #4160
