feat: add ability to generate a local library (#469)

### Summary

Currently, when we have local native modules and views, they become part of the `android` & `ios` source code, this makes upgrading the project to a newer React Native version harder as we also need to consider those changes.

This change lets us create a local library which is not part of the android & ios folders, but a separate directory in the repo, making it self contained. It also adds a new `--no-example` flag to generate the project without example.

More details in this RFC: react-native-community/discussions-and-proposals#702

### How it works

- If we detect a `package.json` in the current folder, we ask user whether they want to create a local library
- If the project is a react-native project, we add entries to `package.json` based on the package manager to link the native library (which creates a symlink in `node_modules`)
- If the project is not a react-native project, we don't modify package.json, but ask user to link based on the project setup - this is relevant for monorepo scenario

### Test plan

- Create a new project with `npx react-native init`
- Run `create-react-native-library` in the project to create a local library
- Import the library in `App.tsx` and use the exported method to verify functionality
- Install dependencies and pods, then run the app on Android & iOS to verify that it works
