no way to dynamically change the breadcrumb title in the navigation

Describe the bug

Sometimes we need to dynamically provide page titles, such as modifyXXX, addXXX, XXXinformation, etc。
I hope to obtain these titles through implementing interfaces, which should also dynamically generate the content of the navgationItem, making it more convenient for us。
Each of these navigationItem has an independent Id for each object.

另：dataContext 也应该提供给接口方法，而不是frameworkViewContent.DataContext，因为frameworkViewContent.DataContext应该是viewmodel，viewmodel的初始化应该交给页面。我们有理由相信初始化过程是有一定业务逻辑的，且viewmode与页面的绑定应该交给页面本身，而不是外部。

所以INavigableView这个接口不应该如此简单！！

再另：internal 关键字是个好东西，但是有些工具方法，工具类能否public；
private bool TryToNavigateWithoutINavigationViewItem；private bool NavigateInternal( 这些方法能否改为 protecte ，否则，即使我继承了NavigateView也不好处理，毕竟这些方法的上层方法都是 public virtual 。

该死的，NavigationStackOnCollectionChanged也是私有的，我清空事件也麻烦。

Start by reviewing INavigableView and the navigation implementation, especially TryToNavigateWithoutINavigationViewItem, NavigateInternal, and NavigationStackOnCollectionChanged. Clarify the intended API for dynamic breadcrumb titles, navigation item content, DataContext, and subclass customization before identifying tests. Done should include an agreed design and coverage for the requested navigation behavior.
