[ParseableInterface] Include "import Swift" in swiftinterface files (#20935) Otherwise we've got a problem with modules that use -parse-stdlib but aren't the stdlib themselves. Ideally we'd /only/ print this in that case, but we don't have that information at this point in the pipeline and I'm not sure it would be a good idea to include it in the set of options we pass through.
