Register a RouteRefreshStatesObserver to be notified of Route refresh state changes.

Immediately refresh current navigation routes. Listen for refreshed routes using RoutesObserver.

Resumes route refreshes that were paused via pauseRouteRefreshes. If route refreshes are not paused, this is a no-op.

Unregisters a RouteRefreshStatesObserver.
