Fixed support for RN 0.76 and other older RN versions

[scarlac]

Removed includesGeneratedCode since it's unreliable and is temporary Added new/old arch code split for Android

Summary

New arch has changed several times, and keeps changing, which makes it extremely difficult to maintain the library and use includesGeneratedCode. This means we have to fork our code base to support the old arch and revert to using generated interfaces. With this change we are also temporarily adding support for old arch back, although it should be considered deprecated at this point.

Issues like #744 should be fixed with this change.

How did you test this change?

Tested on iOS, Android, physical devices, and in sims.

Pull Request Overview

This PR addresses React Native compatibility issues by refactoring the code generation approach and adding support for both new and old React Native architectures. The main purpose is to remove the unreliable includesGeneratedCode configuration and implement separate codepaths for new architecture (Fabric/TurboModules) and old architecture support.

Key changes:

• Removed includesGeneratedCode configuration and switched to standard React Native codegen behavior
• Created separate Android source directories for new architecture (newarch) and old architecture (oldarch) implementations
• Updated iOS imports to use standard generated header paths instead of custom paths
