Preparations for lockscreen launch animations

- Update unlock animations to new spec to make the consistent with
  lockscreen launch animations.
- Introduce disappearing motion for security views which runs before
  we actually dismiss Keyguard.
- If a window is running the un-force-hide animation, treat as it
  would have the wallpaper flag set so the wallpaper stays until
  the animation is completely done.
- Run an animation on the wallpaper if the wallpaper is going away.
