Alex Hunt 85d24122f5 Expose 'react-native/setup-env' to replace InitializeCore (#57475)
Summary:
Pull Request resolved: https://github.com/react/react-native/pull/57475

NOTE: Resubmission of D110890810.

Replace `'react-native/Libraries/Core/InitializeCore'` with an explicit `'react-native/setup-env'` secondary export.

This was previously a special-case path excluded from our ESLint warnings. It is now formalised.

**Changes**

- Add new `src/setup-env.js` entry point and `package.json` mapping.
- Replace references in `packages/metro-config/` and `packages/community-cli-plugin/`.
- Update `warn-on-deep-imports` ESLint rule.

Changelog:
[General][Added] - Add `'react-native/setup-env'` entry point. This replaces the previous side-effectful `'react-native/Libraries/Core/InitializeCore'`.
[General][Deprecated] - Deprecate `'react-native/Libraries/Core/InitializeCore'`. Use `'react-native/setup-env'` instead.
