Add unit test for AutoRestorer<> on smart pointer types.
Test UnownedPtr<> and RetainPtr<>. We cannot operate against std::unique_ptr<> because we need a copyable type. Add test for self-reassignment on going out of scope. Move one test helper class to testing/ so it can be shared among unit tests. Allow it to recognize if it ever gets "destroyed", otherwise we can't be sure Retain/Release applied in the correct order.
