Add GraphNode example for Cxx TMs (#41766)

Browse Source 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/41766

Changelog: [Internal]

Adds a simple example showing a recursive node, stored inside a collection in a Cxx TM.

Currently we can't auto-generate [the necessary C++ Types](https://reactnative.dev/docs/next/the-new-architecture/cxx-custom-types#struct-generator) - but we can add it later if this scenarios becomes really common.
