Andreas Kling cbe75f8251 LibJS: Lazily instantiate "prototype" field on ECMAScriptFunctionObject ...

This field is rarely accessed but we were creating it for every single
script function instantiated.

It's a little awkward but the same optimization can be found in other
engines, so it's nothing crazy.

This avoids creating roughly 80,000 objects on my x.com home feed.
