[Feature] Shadow Receiver XAML Helpers

## Describe the problem this feature would solve
To use the new [Shadow API](https://docs.microsoft.com/en-us/windows/uwp/design/layout/depth-shadow) in XAML without code-behind.  See [blog here for more examples](https://medium.com/@Niels9001/elevate-your-ui-with-themeshadow-703c513fd96a).

## Describe the solution
A way to make it easier to use shadows in apps via XAML. [Initial Proposal](https://twitter.com/XAMLLlama/status/1159892252287590401?s=20) example:

```xml
<Grid x:Name="BgGrid" …>
 <ex:ShadowExt.Receivers>
   <ex:ShadowExt.Receiver Source="{StaticResource BgGridShadow}">
   <ex:ShadowExt.Receiver Source="{StaticResource HeroImageShadow}">
 </ex:ShadowExt.Receivers>
...
</Grid>
```
