新增 %IteratorPrototype%（含 @@iterator 返回自身，经原型链被全部迭代器 继承，it[Symbol.iterator]() === it 恒等）与 %ArrayIteratorPrototype%/ %MapIteratorPrototype%/%SetIteratorPrototype%/%StringIteratorPrototype%/ %RegExpStringIteratorPrototype%（链到 %IteratorPrototype%）；Array/Map/Set/ TA/String/matchAll 迭代器包装统一挂对应原型；补 Array/String 的 @@iterator 别名绑定。集合迭代器原型不含 return 方法（规范集合迭代器无 return）。
