This updates the codesigning test to account for iOS and macOS binaries in the artifact cache that are _expected_ to not be codesigned. In https://github.com/flutter/engine/pull/54414 we started bundling dSYM (debugging symbols) within Flutter.xcframework, a requirement for App Store verification using Xcode 16. We did the same for macOS in https://github.com/flutter/engine/pull/54696. Unlike the framework dylib, dSYM contents are not directly codesigned (though the xcframework containing them is).
