Automatically hide "enable precise location" banner

[jill-cardamon]

#2693 prompts the user (running iOS 14) to enable precise location to navigate. Currently, the banner hides after 20 seconds. However, it would be better if the accuracy authorization banner persists until precise location is enabled, then automatically hides.

We are already able to observe the notification for a change of accuracy authorization. StatusView.hide(delay:animated:) needs to be exposed and used in NavigationViewController.navigationServiceDidChangeAuthorization(_ service:didChangeAuthorizationFor:) to hide the authorization accuracy banner at the right time.
