Summary: changelog: Introduce setNativeProps to Fabric Add support for `setNativeProps` in Fabric for backwards compatibility. It is still recommended to move away from `setNativeProps` because the API will not work with future features. We can make step [Migrating off setNativeProps](https://reactnative.dev/docs/new-architecture-library-intro#migrating-off-setnativeprops) in migration guide optional.
