[JSC] Add support for Atomics.waitAsync

Summary
[JSC] Add support for Atomics.waitAsync
Florens Verschelde
Reported

We at StackBlitz are using Atomics.waitAsync (
https://github.com/tc39/proposal-atomics-wait-async
, apparently stage 3 and shipped in Chromium) on stackblitz.com to power our Node.js-in-the-browser port (called WebContainers). Firefox doesn't implement Atomics.waitAsync either, but we were able to implement a polyfill using workers-in-workers, something that is not possible in Safari at this time. The lack of Atomics.waitAsync in WebKit is one of the things stopping us from offering WebContainers to users of Safari and other WebKit-based browsers at this time. (Others include
bug 174931
,
bug 238442
, and possibly more we haven't identified yet.)

Given that this bug is also relevant to the implementation of RegExp lookbehind, please also take time to look at
https://bugs.webkit.org/show_bug.cgi?id=174931
which is also needed for a higher priority. It's also noted that Atomics.waitAsync has been shipped in both Chromium and Firefox now.
