Preserve the warning to use `internal import` instead of `@_implementationOnly` to imports of Swift modules only. This warning can be noisy, limiting it may prevent users from outright learning to ignore it. Typical uses of an `@_implementationOnly` import of a clang module is often for a project internal module instead of a layering concern as we have with Swift module targets. We can leave legacy uses of `@_implementationOnly` in peace for now.
