[Fabric] Reanimated events are not sent on the Fabric "bridgefull" IOS build

[k4rpen]

Description

In our project, navigation is based on Reanimated events (such as onWillAppear, onWillDisappear, onTransitionProgress), after enabling Fabric + bridgefull, we saw that events on iOS stopped being sent

Sandbox with problem reproduction
https://github.com/k4rpen/react-native-screens-issue

For example, I added receiving the onWillAppear event in the ReanimatedNativeStackScreen

const onWillAppearReanimated = useEvent(
    event => {
      'worklet';
      console.log('!!!onWillAppearReanimated', event);
    },
    [Platform.OS === 'android' ? 'onWillAppear'
      : ENABLE_FABRIC 
      ? 'onWillAppear' 
      : 'topWillAppear'
    ],
  );
  
...
  
onWillAppear={() => console.log('!!!onWillAppear JS')}
onWillAppearReanimated={onWillAppearReanimated}

These events work on Android:

old-arch

Fabric + bridgeless (it is also interesting that events are doubled)

Fabric + bridgefull (it is also interesting that events are doubled)

---

On iOS, they don't work only on bridgefull:

old-arch

bridgeless

bridgefull

Steps to reproduce

1. Enable Fabric
2. Disable bridgeless mode
