Manually dismiss popups when the window moves, or the SUI scrolls (#10922)
## Summary of the Pull Request

BODGY!

This solution was suggested in https://github.com/microsoft/microsoft-ui-xaml/issues/4554#issuecomment-887815332.

When the window moves, or when a ScrollViewer scrolls, dismiss any popups that are visible. This happens automagically when an app is a real XAML app, but it doesn't work for XAML Islands.

## Detailed Description of the Pull Request / Additional comments

Unfortunately, we've got a bunch of scroll viewers in our SUI. So I did something bodgyx2 to make our life a little easier.

`DismissAllPopups` can be used to dismiss all popups for a particular UI element. However, we've got a bunch of pages with scroll viewers that may or may not have popups in them. Rather than define the same exact body for all their `ViewChanging` events, the `HasScrollViewer` struct will just do it for you!

Inside the `HasScrollViewer` stuct, we can't get at the `XamlRoot()` that our subclass implements. I mean, _we_ can, but when XAML does it's codegen, _XAML_ won't be able to figure it out.

Fortunately for us, we don't need to! The sender is a UIElement, so we can just get _their_ `XamlRoot()`.

So, you can fix this for any SUI page with just a simple 

```diff
-    <ScrollViewer>
+    <ScrollViewer ViewChanging="ViewChanging">
```

```diff
-    struct AddProfile : AddProfileT<AddProfile>
+    struct AddProfile : public HasScrollViewer<AddProfile>, AddProfileT<AddProfile>
```

## Validation Steps Performed

* the window doesn't close when you move it
* the popups _do_ close when you move the window
* the popups close when you scroll any SUI page
