The BottomNavigationBar's `sizeThatFits:` method should ignore its
current safe area. The superview or view controller should be
responsible for setting the bar's bounds and positioning it. The bar

This change includes a migration flag that clients can use to enable the new behavior. This allows the change to be landed internally without making breaking changes to client code. Clients can then update their layout code to correctly account for the safe area.

This is a breaking change.
