[JSC] Support Inlined InternalMicrotask reaction with Promise
https://bugs.webkit.org/show_bug.cgi?id=314788
rdar://177040942
Reviewed by Sosuke Suzuki.
313220@main now offers yet another JSCell* space in JSPromise, thus we
can just store JSPromise* as well when adding inline InternalMicrotask
reaction. This patch supports it and now all InternalMicrotask reaction
can be inlined when it is only one reaction in the promise.
Test: JSTests/stress/dynamic-import-inline-microtask-result-promise.js
* JSTests/stress/dynamic-import-inline-microtask-result-promise.js: Added.
