TM iOS: Install TurboModule system in RNTester (pod) by default

Summary:
For CocoaPods variant only: install TurboModule binding so that sample modules can start using it. This commit only installs `global.__turboModuleProxy` - no sample module is provided.

Note: RNTester.xcodeproj will NOT have TurboModule enabled, due to complication in the .xcodeproj setup (doable, but maybe for some other time...)

To test:

```
console.error(global.__turboModuleProxy == null ? 'BOO' : 'YAY!');
```

Saw `YAY!` in RNTester pod version.
