Add a mono-repo task orchestration tool (like Nx, TurboRepo or Wireit)

We're starting to have scripts spread across the various packages that need to be ran in the right sequence for everything to work as expected.

One example is the packages/react-native-node-api-modules package, which needs the following scripts ran after checkout:

npm run copy-node-api-headers
npm run build-weak-node-api
npm run generate-weak-node-api-injector

I think it's about time that we add a tool to orchestration running these scripts across the packages of the mono-repo.

I'm getting started on this now - I will likely pick Nx.
