[JSC] Align Iterator#join to the latest spec
https://bugs.webkit.org/show_bug.cgi?id=321270
rdar://184321382
Reviewed by Yijia Huang.
Align Iterator#join implementation more to the spec.
1. even if undefined/null element exists, we still need to append a
separator. This fixes a test262 failure.
2. For efficiency, use JSRopeString::RopeBuilder.
