$262.IsHTMLDDA's [[Call]] behavior is underspecified

[linusg]

https://github.com/tc39/test262/blob/main/INTERPRETING.md only covers what should happen when it is being called with no arguments or an empty string and not what happens otherwise, as a result different engines/test262 harness implementations disagree on this:

• JSC: Returns null unconditionally
• V8: Returns null unconditionally
• Kiesel: Returns null unconditionally
• QuickJS: Returns null unconditionally
• LibJS: Returns undefined
• SpiderMonkey: Throws

In practice it seems that nothing relies on this but I think it would be nice to get everyone on the same page.
