Cedric van Putten 4a4cceef25 Fix hardcoded path to codegen cli for monorepos (#35430)
Summary:
Fixes https://github.com/facebook/react-native/issues/35429

This fix is fairly straightforward. Instead of hardcoding two separate paths for this repo or a simple user's project, we ask Node to resolve `react-native-codegen`.

Because `react-native-codegen` is moved [into the `/packages/*` folder](https://github.com/facebook/react-native/blob/main/package.json#L104), it's part of a workspace in this repository. That means that this fix works not only for monorepos in general but also resolves the right path within the react native repository.

You can test this out yourself when running this command in either the root, or any other workspace in this repository:
```bash
node --print "require('path').dirname(require.resolve('react-native-codegen/package.json'))"
```

I've tested this on Node 16 and 18, and seems to work nicely. Note that you _**have to specify `react-native-codegen/package.json`**_. That's because the `react-native-codegen` package itself is technically invalid; it's missing an entry point within the package (no `main`). When running `node --print "require.resolve('react-native-codegen')"` Node can't resolve the main entry point, and will fail during this process.
