1. [ios] fix memory leak in Border …

   While looking at the customer sample, we found an issue with
   `BorderHandler`:
   
   * `ContentView` -> via `LayoutSubviewsChanged`
   * `BorderHandler` ->
   * `ContentView`
   
   Creating a cycle & memory leak on iOS and Catalyst. We could reproduce
   this in a device test.
   
   It appears the event only did this:
   
       void OnLayoutSubviewsChanged(object? sender, EventArgs e)
       {
           PlatformView?.UpdateMauiCALayer();
       }
   
   And so instead, we can just call the extension method directly:
   
       this.UpdateMauiCALayer();
   
   And the leak is gone!
