CC Animation: Erase old animation system.

Basically, specialize all the code as if:
- use_compositor_animation_timelines is always true.
- Layer::layer_animation_controller_ is always nullptr.
- LayerImpl::layer_animation_controller_ is always nullptr.
- LayerTreeHost::animation_registrar_ is always nullptr.
- LayerTreeHostImpl::animation_registrar_ is always nullptr.

Next CL: Erase cc::LayerSettings everywhere.
