Janic Duplessis d5db2cb5d1 Build rn-codegen in a temporary directory (#30292) ...

Summary:
When running yarn install from the codegen directory it will reinstall all dependencies for the react-native workspace inside the react-native package. In my case this caused issues with metro because it would now have 2 copies of it (node_modules/metro and node_modules/react-native/node_modules/metro).

To avoid this copy the react-native-codegen source in a temporary directory and yarn install from there, then copy the built files back.

## Changelog

[Internal] - Build rn-codegen in a temporary directory

Pull Request resolved: https://github.com/facebook/react-native/pull/30292

Test Plan: Tested the script in an app with codegen enabled. Fresh install with rn-codegen not built, made sure no extra modules are installed under node_modules/react-native/node_modules.
