Enable Kotlin build in OSS (#33160)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/33160

Enables Kotlin build in RNAndroid, while adjusting the package structure to help with path/package inconsistency.

Moves `react/uimanager/interfaces` files into `react/uimanager` to make sure package name matches with file location and updates Buck configuration to still include it as a separate target.

Changelog: [Android][Changed] - Moved `com/react/facebook/uimanager/interfaces` files into `com/react/facebook/uimanager` to enable Kotlin build
