feat!: support new React Native architecture (#439)

FEATURES:
 - New React Native Architecture Support
 - Adds support for the new React Native architecture.
 - Uses codegen to generate the native interop layer for TurboModules and Fabric views.
 - Navigation SDK Upgrades
 - Android: upgraded from 7.1.0 to 7.3.0
 - iOS: upgraded from 10.6.0 to 10.7.0

BREAKING CHANGES: 
 - Legacy Architecture Removed
   - Removes support for the legacy React Native architecture.
 - API changes:
   - View Event Handlers as Props: Instead of using mapViewCallbacks and navigationViewCallbacks wrapper objects, event handlers are now passed directly as first-class view props.
   - View Flags as Props: View flags have been moved from viewControllers to view props. For example, the headerEnabled state can now be managed directly via a view prop, instead of calling navigationViewController.setHeaderEnabled(value).
   - Migrate from configuring listeners via one combined setter call to setting each listener via its own dedicated setter.
   - Updated the minimum Kotlin version to 2.2.10. Our recommended Android Gradle Plugin (AGP) is now 8.10.0 and Gradle is now 8.11.1.
   - Support for React Native versions below 0.79.x are dropped.
