Ensure NativeAnimatedHelper cannot be setup incorrectly (#37157)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37157

## Context
NativeAnimatedHelper must be set up in a very particular way:
- On iOS in Bridgeless mode, it must use NativeAnimated**Turbo**Module.
- Everywhere else, it must use NativeAnimatedModule.

## Problem
For some unknown reason, NativeAnimatedModule was getting loaded on D44933587.

## Changes
This diff makes the aformentioned error impossible. It moves the module load gating logic into the two NativeModule spec files.
