Carousel control doesn't expose Selection in UI Automation tree

[jamesmcroft]

Describe the bug

A clear and concise description of what the bug is.

When querying the Carousel control using a tool for analyzing the UI Automation tree, the control doesn't expose the currently selected item. This is due to the nature of the inherited ItemsControl which doesn't expose properties for the selected item (these have been implemented as part of the custom control).

As the control doesn't expose the underlying child CarouselItem in the UI Automation tree also, it's not possible to find the selected item.
