Subject: [PATCH] Fix codegen for iterable's forEach method

The `forEach` method installed on iterable DOM interfaces uses SpiderMonkey's self-hosted implementation of `Array.prototype.forEach`, but it has the wrong value for `nargs`, causing failing asserts in debug and wrong behavior in release builds.

Fixes #13451
