Remove SampleTurboCxxModule example

Summary:
Changelog: [Internal]

The sample is from an outdated approach of enabling C++ Modules in RN which is not recommended anymore.

Prefer C++ Turbo Modules if you need to expose / access C or C++ APIs in RN apps:

https://reactnative.dev/docs/the-new-architecture/pure-cxx-modules

It is not included in any RNTester app at this time
