Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

LibJS: Implement Iterator.from and the WrapForValidIteratorPrototype Iterator.from creates an Iterator from either an existing iterator or an iterator-like object. In the latter case, it sets the prototype of the returned iterator to WrapForValidIteratorPrototype to wrap around the iterator-like object's iteration methods.
