Build codegen package in pod install (#32678)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/32678

In D32420306 (3d8b5a35f9) (3d8b5a35f9), I added a phase which uses a codegen, but it assumed that the codegen package has already been built. This diff fixes the issue where it checks and build the codegen packaage.

I also reverted the change that I made for the circle CI test since it now builds the codegen when running pod install.
