Reduce side-effects of AppRegistry (#53054)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53054

Changelog: [internal]

We eagerly require `AppRegistry` from environment initialization (`InitializeCore`) because it has some side-effects that are necessary for error reporting (see https://github.com/facebook/react-native/issues/34649 and https://github.com/facebook/react-native/pull/34650), but this change makes a lot of modules to be eagerly initialized.

This reduces that to avoid loading modules that not necessary for environment setup, which allows us to do things like setting up feature flags before modules like `View` and `Text` have been initialized.
