Issue: [iOS][Old Arch][Codegen] - Codegen breaks pod install
Labels: Platform: iOS,Newer Patch Available

### Description

Hi everyone! 👋

We are currently upgrading our application **from version .73.8 to .75.4** and we've noticed something weird.
With the new version, if we run `pod install`, **_now Codegen gets executed differently than before._**

This would be fine if we actually enabled the new architecture, but we didn't and **it breaks the pods install phase** because some libraries are compatible with the new architecture but present **issues in the Spec** file that Codegen refers to.

> So we can't install pods using the old architecture with libraries that present issues on Spec files because Codegen can't properly parse them (I guess)

I took the time to look into the changes between version .73.x and .75.x and **I've noticed that this commit** was included: [Defragment Codegen in OSS between Old and New Architecture](https://github.com/facebook/react-native/commit/1204696f08c91e17154d5b9c946d7fe8532510de) and **it changes the following file**: [codegen.rb](https://github.com/facebook/react-native/blob/main/packages/react-native/scripts/cocoapods/codegen.rb) by removing the `new_arch_enabled` check in the `run_codegen` function.

> Doing so means that if we run the same project on version .73 it works fine, but if we run it from version .74 onward it breaks on the old architecture with any library that has a Spec file that is broken

I don't have a complete overview of how Codegen gets executed, by I think that we should revert this check for the sake of any project that can't migrate right away due to lock-ins: may them be by libraries or vendor code such as third party sdks.


### Steps to reproduce

1. Init a new project with `npx @react-native-community/cli@latest init RN75 --version 0.74 --pm npm`;
2. Install any library such as `npm install --save-dev react-native-webview`;
3. Break the Spec file in any way, in our case we can break: `react-native-webview`'s Spec file by adding a Tuple that isn't supported yet; (Example down below)
4. Run `pod install`;
5. See **Codegen** error;

Example:

```ts
// node_modules/react-native-webview/src/NativeRNCWebViewModule.ts

import type { TurboModule } from 'react-native';
import { TurboModuleRegistry } from 'react-native';
import { Double } from 'react-native/Libraries/Types/CodegenTypes';

export interface Spec extends TurboModule {
  isFileUploadSupported(): Promise<boolean>;
  shouldStartLoadWithLockIdentifier(
    shouldStart: boolean,
    lockIdentifier: [Double] // We change this type from Double to [Double]
  ): void;
}

export default TurboModuleRegistry.getEnforcing<Spec>('RNCWebViewModule');

```
