[gnome-boxes] Switch to per-actor easing states

[Alexander Larsson <alexl src gnome org>]

commit a6a6909148c4122c2ad47fccb5330ffafc10de02

    Switch to per-actor easing states
    
    Instead of using layout animations on the overlay_bin we
    use the new clutter support for per-actor default easing
    states. This means we can now disable animations of the
    thumbnail in properties view after the initial animation.
    
    Also, its possible that the layout manager animation
    feature will be removed, so better not rely on it.
