Robert Moore 93700ab4d9 [Tabs] Improve accessibility for TabBar example. (#8983)
The Tab Bar View Controller with Interface Builder example had no way to
dismiss with Voice Over, disappearing labels, and too much code.  Provides an
AppBar with back button, labels on every child view controller, and better
support for Dynamic Type.
