RazorViewTopLevel will now test keys first on Code, then Key as a backup

This is an android specific hack. the chrome browser event sends an empty string on Code property so this will test both Code and Key properties to match to an Avalonia key. If the user is on a sane system then Code will be used to Key match, else it will failover to try and match with Key.
