[gnome-shell/wip/carlosg/osk-gesture-feedback: 24/32] layout: Move keyboard slide animation to keyboard

    layout: Move keyboard slide animation to keyboard
    
    The animation handling is kinda split between layout (for the
    keyboard slide), and keyboard (for the focus window slide). It
    would be nice to have more fine grained control on those, so
    move the animation handling altogether to keyboard.js as a start.
    
    This is roughly similar, except that transformations apply to
    the Keyboard actor, instead of the keyboardBox (its parent). We
    now queue a relayout after the animation in order to update the
    chrome tracking.
    
    The only layering break now is that we emit
    layoutManager::keyboard-visible-changed in keyboard.js, its
    purpose will be dropped in future commits, so leave it there for
    now.
