feat!: support new React Native architecture

[jokerttu]

Starting with React Native version 0.76, the New Architecture is enabled by default, introducing significant changes to the framework's internals. This PR updates the package to support the New Architecture and drops support for the legacy architecture.

Resolves #338

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.

CHORE CHANGES:

• Converts Android example app code to Kotlin.
• Adds a code formatter for Kotlin files (used in the example app).
• Updates the README to document New Architecture support.
• Adds MIGRATING.md documentation file for migration process.

Hello @jokerttu, I'm wondering if this MR is still in progress, as it has been submitted for approval for about a month?

Yes, the process is still ongoing.
The new architecture has been implemented and is working in the example app. However, we are still in the middle of resolving issues with CarPlay support, particularly with multi-scene applications. Related issue: facebook/react-native#46184
