[JSC] Use JSSlimPromiseReaction for JSAsyncGenerator queue
https://bugs.webkit.org/show_bug.cgi?id=319393
rdar://182224083
Reviewed by Keith Miller.
We can stop using JSFullPromiseReaction and use JSSlimPromiseReaction if
we apply the following changes in JSAsyncGenerator.
1. We can just use circular singly-linked-list for queueing. Since
queueing is always just enqueue and dequeue, we do not need to have
doubly-linked-list.
2. Pack resumeMode into JSSlimPromiseReaction's payload.
