This fixes sudden compiler errors that are emitted when trying to use CoreText.framework with C++ interop enabled. When Swift is trying to rebuild a dependency module from its textual interface, it should not complain on usages of C enums in public Swift APIs. This still leaves the resilience safety guardrail enabled for C++ scoped enums. rdar://143215914
