Use codegen from source in default iOS template apps

Summary:
Add the `react-native-codegen` source to the `react-native` npm package.
Instead of using `react-native-codegen` from npm, the iOS app template will now build the package from source. Doing so removes the need to carefully time `react-native-codegen` npm releases to oss `react-native` releases, as the codegen and the oss release will be cut at the same time.

Changelog: [Internal] - Removed react-native-codegen dependency from iOS app template
