iOS,macOS: Add list of expected-unsigned binaries (flutter#154636)

This updates the codesigning test to account for iOS and macOS binaries in the artifact cache that are _expected_ to not be codesigned.

In flutter/engine#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 flutter/engine#54696.

Unlike the framework dylib, dSYM contents are not directly codesigned (though the xcframework containing them is).

Issue: flutter#154571

This is a cherry-pick of flutter#154591 to the flutter-3.24-candidate.0 branch.
