feat(router): add navigationSource and restoredState to NavigationStart event (#21728)

Browse Source 
Currently, NavigationStart there is no way to know if an navigation was triggered imperatively or via the location change. These two use cases should be handled differently for a variety of use cases (e.g., scroll position restoration). This PR adds a navigation source field and restored navigation id (passed to navigations triggered by a URL change).
