[JSC] Iterator#includes should propagate a thrown error in |IteratorClose|
abstract operation on matching the target value

Reviewed by Keith Miller.
This is a bug by the wrong implementation in bug 309883.
According to [the spec](https://tc39.es/proposal-iterator-includes/),
in the step 10-d, we should propagate an error happening in `IteratorClose`
abstract operation.
* JSTests/stress/iterator-prototype-includes.js:
This adds some cases that `IteratorClose` throw an error.
