fix(ivy): detach ViewRef from ApplicationRef on destroy (#27276) 

Currently we store the `_appRef` when a `ViewRef` is attached, however we don't use it for anything. These changes use it to detach the view from the `ApplicationRef` when it is destroyed. These changes also fix that the `ComponentRef` doesn't remove its `ViewRef` on destroy.
