Create new arch module template: cpp-lib (#12481)

## Description Adds a new `cpp-lib` template designed to be applied on top of the new projects created by the (now recommended) `create-react-native-library` script. Also updates the `cpp-app` template to be able to autolink and run these new libraries. ### Type of Change - New feature (non-breaking change which adds functionality) - This change requires a documentation update ### Why Devs need to add windows support to native modules in a way which can be consumed by the new arch RNW apps (i.e. the `cpp-app` template). Resolves #12480 ### What Create a new `cpp-lib` template which can be applied on top of the template created by `npx create-react-native-library`, adding Windows support for a turbo module. It will also automatically apply the `cpp-app` template to the example project if it exists. ## Screenshots <img width="441" alt="image" src="https://github.com/microsoft/react-native-windows/assets/10852185/f5f31727-a233-419c-8afe-ad91f797abb2"> ## Testing Verified the new template could be applied to a fresh library created by `create-react-native-library` and that example app autolinks, builds, and runs correctly. ## Changelog Should this change be included in the release notes: yes Created a new arch module template: cpp-lib
