Description
RootViewPanel is useful for product view manager which need to manage keyboard/touch inputs.
Type of Change
Why
Before this change it's not possible to make a view manager in product code for XAML controls such as Popup/Flyout. This is why it's not possible to make something like FlyoutViewManager in product code as it requires TouchEventHandler/PreviewKeyboardEventHandlerOnRoot which are not exposed in the RNW ABI.
What
Created RootViewPanel class which is exposed via RNW ABI for use in product view managers.
Testing
At Meta we've used this class to create a product view manager which uses XAML Popup. In the view manager's AddView method you can add child views onto a RootViewPanel.
Changelog
Should this change be included in the release notes: no
