Adds Atomics.waitAsync, the async version of Atomics.wait. Atomics.waitAsync allows programmers to wait on a SharedArrayBuffer location in the same fashion as Atomics.wait but returns a Promise instead.
Motivation
Atomics.wait blocks the thread and cannot be used on the main web browser thread, where blocking is disallowed. This makes coordination via SharedArrayBuffers between the main thread and worker threads more ergonomic.
