Summary:
This pull request aims to remove iOS 11 version check which is no longer needed.
The minimum iOS deployment target for React Native is `iOS 11` but we still have iOS 11 version check like below.
```
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 110000 /* __IPHONE_11_0 */
if (available(iOS 11.0, *)) {
```
> React Native apps may target iOS 11.0 and Android 5.0 (API 21) or newer.

------
If there is a team motivation to remove the deprecated methods and classes before iOS 10, I can continue the work in this pull request or in the continuing pull requests.
We have deprecated warnings for these in the project.
- `UIUserNotificationSettings`
- `UILocalNotification`
- `topLayoutGuide` and `bottomLayoutGuide`
- `automaticallyAdjustsScrollViewInsets`
