Instead of each IDL interface wrapper having its own set of all the attributes and functions, they are moved to the prototype. This matches what we already do in LibJS. Also, this should be spec compliant with the web as well, though there may be *some* content out there that expects some things to be directly on the wrapper since that's how things used to work in major browsers a long time ago. But let's just not worry about that for now. More work towards #4789
