[libhandy/wip/exalm/paginator-animate: 69/78] carousel-box: Remove hdy_carousel_box_animate()

[Alexander Mikhaylenko <alexm src gnome org>]

    carousel-box: Remove hdy_carousel_box_animate()
    
    It would be good to ensure we only ever animate to child positions in
    future, so only allow that.
