Missing children in navigation bar

#8762 unearthed some issues with navigation bar items. We should be creating childItems for more node types.

• Modules
  • navbar_contains-no-duplicates: Foundation
  • navigationBarItemsModules: B and C
• Interfaces
  • navigationBarItemsInsideMethodsAndConstructors: LocalInterfaceInConstructor and LocalInterfaceInMethod
• Enums
  • navigationBarItemsInsideMethodsAndConstructors: LocalEnumInMethod
  • navigationBarItemsItems: Values
  • navbar01: Values
• Classes
  • navigationBarItemsItems: Point
  • navbar01: Point

This should be resolved by #8780, #8811, #8813, and #8814. Note that whenever one is merged the others will need to be updated to get their verify.navigationBarCount calls right. Then we can merge #8812 to make that simpler in the future.
