Subject: [PATCH] Fix useWindowDimensions not updating because of delayed
 applicationState update on iOS devices (#46353)

Summary:
### Issue
When a real device is oriented into landscape and the user locks the screen during said orientation incase the user rotates back to previous orientation and unlocks the screen `useWindowDimensions` will not get the correctly updated values. This is due to `applicationState` being equal to UIApplicationStateInactive still when `interfaceFrameDidChange` gets called.

### Fix
`didUpdateDimensions` on iOS. Now correctly emits the dimension values after the device has been oriented and device has been locked. By adding `UIDeviceOrientationDidChangeNotification` to `NSNotificationCenter`

## Changelog:
[IOS] [FIXED] - Emit didUpdateDimensions correctly

```
  // RCTDeviceInfo.mm

  // Adds the interfaceFrameDidChange to UIDeviceOrientationDidChangeNotification
  [[NSNotificationCenter defaultCenter] addObserver:self
                                           selector:selector(interfaceFrameDidChange)
                                               name:UIDeviceOrientationDidChangeNotification
                                             object:nil];
```

Test Plan:
### ***Note***: This doesn't seem to be replicable on simulators. It only happens on real iOS devices.

### Before change:

Rotate Device > Lock Screen > Rotate back to portrait > Unlock phone
