`ListViews` should not recycle the first view or the currently focused view
Current behavior
Currently, any view that's not visible and is not within CacheLength will be recycled.
Expected behavior
On WinUI, the first view is just never recycled. I'm not sure if there are specific scenarios where it is, but from my testing it seems like it just never gets recycled. Also, if a view is currently focused (either through mouse or keyboard), the view is never recycled even if scrolled out of view. This makes sense because we wouldn't want to lose focus just because of scrolling i.e. if we focus something, scroll away and back, the focus shouldn't change. The moment the focused out-of-visible-area view loses focus, it gets recycled.
How to reproduce it (as minimally and precisely as possible)
Most listview samples will do, e.g. ListView_Aligned_Left.
