feat: generate apple_resource_bundle for Objc targets (#696)

- Handle resources for clang targets.
- Update `resources_example` to include [GoogleSignIn-iOS
SDK](https://github.com/google/GoogleSignIn-iOS). The
`GoogleSignInButton` uses resources that are associated with an Objc
target.
- Add UI test for `resources_example` to ensure that the app launches
and the resources are found.
