Enable useFabricInterop by default for internal apps (facebook#50295)

Summary:
Pull Request resolved: facebook#50295

Enabling `useFabricInterop` by default for internal apps since before D71582553 iOS wasn't using useFabricInterop in it's codebase and old architecture with Interop enabled is harmless.

This is to keep the current behaviour consistent.
