## 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.

### 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 microsoft#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.

## 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
