Switch module codegen to use yarn_workspace_binary. (#34015)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/34015

I noticed this was a very slow part of my build because each instance of the binary would run its own yarn install. Instead use the yarn_workspace approach to share a single yarn setup.
