Kevin Gozali a3df286247 Move TurboModuleRegistry (JS) to github
Summary:
Moved the JS wrapper function to github. To access a TurboModule from JS:

```
export interface Spec extends TurboModule {
  +func1: () => number,
}

const module = TurboModuleRegistry.get<Spec>('SampleTurboModule');
```

This assumes:
* the binding on the native side has been installed properly, i.e. `global.__turboModuleProxy` needs to be installed properly.
* the module `SampleTurboModule` is registered properly in native.

More instructions will be provided later.
