Mark all of the AppBar implementation component examples as dragons. (#…

…3596)

ButtonBar, FlexibleHeader, HeaderStackView, and NavigationBar are all implementation details of AppBar. While these components can be used on their own, in practice we expect most typical usage to rely on AppBar. FlexibleHeader is a bit blurry in that there is often value in relying on it solely, but because it is not a true concept in the spec and its behavioral demos largely overlap with AppBar's, it is now a dragons demo.
