[webidl] @@toStringTag property attributes (#54)

> **Editorial note**
Should define whether @@toStringTag is writable, enumerable and configurable. All @@toStringTag properties in the ES6 spec are non-writable and non-enumerable, and configurable.

I think we really need to define these. Matching the values on the builtin properties is probably good, because matching ECMAScript is a good plan.

The other issue with these properties, is making `InterfacePrototype.@@toStringTag === "InterfacePrototype"` while `Interface.@@toStringTag === "Interface"` --- I don't believe we want to give `Interface` an instance property `@@toStringTag`, so the alternative is making `@@toStringTag` a getter which returns a distinct value depending on the receiver --- but that's problematic for interfaces which are inherited.

So yeah, I don't think we have a good answer for these semantics right now. It's probably worth discussing it a bit
