Remove the target specific binary and instead compile a test binary on the fly. Because this test is restricted to macOS platforms, we know that we assume that we will have a compatible Objective-C runtime at our disposal. Use that to create a stub library for testing `NSClassFromString`. This allows this test to execute on ARM64.
