Split NativeStatusBarManager into NativeStatusBarManager{Android,IOS}

Summary:
The `StatusBarManager` NativeModule does not have a uniform API on iOS and Android. In particular, the `setStyle` and the `setHidden` methods have an additional parameter on iOS:

```
/**
 *  - statusBarStyles can be:
 *    - 'default'
 *    - 'dark-content'
 *    - 'light-content'
 */
+setStyle: (statusBarStyle?: ?string, animated: boolean) => void;
/**
 *  - withAnimation can be: 'none' | 'fade' | 'slide'
 */
+setHidden: (hidden: boolean, withAnimation: string) => void;
```

If we keep the NativeModule spec the same between the two platforms, we'd have to keep the second parameter optional for both methods. This works for `setHidden`, because the second parameter is a string, and optional strings are allowed. However, for `setStyle`, the second parameter is a number, and we don't support optional numbers/booleans on Android in the NativeModule system. If we keep the optional number, then the following check triggers in our RedBox tests on iOS, which makes them fail: https://fburl.com/diffusion/b7adezd9.

So, since the two specs are sufficiently different, I figured that the easiest path forward is to split them apart.

Changelog:
[iOS][Changed] - Separated NativeStatusBarManager into NativeStatusBarManager{IOS,Android}
