Ensure that classes and enums don't reference an implementation-only imported dependency unless they are themselves marked as
@_implementationOnly. This is similar to the logic applied to structs in #85179, ensuring their memory layout visible to clients doesn't depend on the hidden dependency. Also extend checking for super types to structs.This remains gated behind the experimental feature flag
CheckImplementationOnly.
