[RN] Update ReactPrivate and InitializeCore imports (0.87 Strict API) (#36986)
## Summary Migrate internal `Libraries/` import subpaths from `react-native` to the incoming dedicated entry points in React Native 0.87. **Motivation** See [**RFC0894: Removing deep imports from react-native**](https://github.com/react-native-community/discussions-and-proposals/pull/894) **Changes** The `react-private-interface` entry point has been created explicitly for the private contract between React ↔ React Native, and is 1:1 with the previous `ReactNativePrivateInterface` module. Both of the below `Libraries/` paths still exist, but are deprecated — this is a lagging migration that will enable cleanup in a future RN version. - `react-native/Libraries/Core/InitializeCore` → `react-native/setup-env` [react/react-native#57475](https://github.com/react/react-native/pull/57475) - `react-native/Libraries/ReactPrivate/ReactNativePrivateInterface` → `react-native/react-private-interface` [react/react-native#57495](https://github.com/react/react-native/pull/57495) ## Test Plan Flow
