CustomAttributes disagrees with GetCustomAttributes on array types

[MichalStrehovsky]

        Console.WriteLine("** CustomAttributes");
        foreach (var a in typeof(object[]).CustomAttributes)
            Console.WriteLine(a.AttributeType);
        Console.WriteLine("** End");

        Console.WriteLine("** GetCustomAttributes");
        foreach (var a in typeof(object[]).GetCustomAttributes())
            Console.WriteLine(a.GetType());
        Console.WriteLine("** End");

This will print:

** CustomAttributes
System.SerializableAttribute
** End
** GetCustomAttributes
** End

This is trivial to fix but this code is in the process of getting unified with native AOT so do not assign to copilot this year (pull requests are in flight right now and there might be more and this will be a very unnecessary merge conflict).
