StackView should add back action.

[adamvy-google]

It's tedious and error prone to be adding the back action in every view that might be pushed onto the stack. The stack view should be adding the action to any view that isn't top level. At the top level it can place the menu action instead.

This ties into the new toolbar, since we used to push a new toolbar on with
each view (and hence the back action). Now the ToolbarView itself can take
care of it.
