This makes sure that the compiler does not emit `-enable-experimental-cxx-interop`/`-cxx-interoperability-mode` flags in `.swiftinterface` files. Those flags were breaking explicit module builds. The module can still be rebuilt from its textual interface if C++ interop was enabled in the current compilation. rdar://140203932
