Switch drag data to be stored in the Properties rather than datatype itself
On windows 10 19041 I am seeing https://github.com/microsoft/CsWinRT/issues/807 clearly drag drop must be fixed on W11 as I assume dragdrop works in app on some platform. This fix transitions keeping the dragdrop data as a format to be stored as a property. We are storing relatively little data so I do not see any downside to this transition.
Simplified some of the casting/conditionals as well.
