feat: added some options in Linking.addEventListener

[hellohublot]

Summary:

Unifies openURL, openURL:sourceApplication:annotation:, and continueUserActivity: handling by routing all through postNotificationWithURL, allowing full context (sourceApplication, annotation, activityType, etc.) to be passed to JS.

Fixes: #31283

Changelog:

[IOS] [CHANGED] Unify URL handling in LinkingManager and include full options in event payload

Test Plan:

Tested opening URLs via:

• Opened deep links from external apps (rntester://)
• Confirmed full payload received in JS (url, sourceApplication, activityType, etc.)

const [event, setEvent] = useState({})
useEffect(() => {
  Linking.addEventListener('url', event => {
    setEvent(event)
  })
}, [])
return (<Text style={{ textAlign: 'center', marginTop: 200 }}>{JSON.stringify(event)}</Text>)

Expected Behavior:

_ios.mp4

• sourceApplication is nil when the link is opened from a system app (e.g. Safari or Mail). It’s only available when opened via a third-party app due to iOS privacy behavior.
• I’d suggest not including options in the official documentation, as its keys are not fixed.
