Tame Promise.all for causal tracing

[kriskowal]

Promise.all does not currently participate in our causal graph construction with assert.note. We could wrap Promise.all to that effect.

[mhofman]

Would this wrap a rejection in promise.all to the capture the caller? I hope that someday we can have a more holistic approach to this problem that patching some APIs. Maybe AsyncContext can help somehow, but I'm not sure it can given the current API.

Also to clarify, this would keep the semantics of short circuiting on rejections? We should similarly find a way to annotate unhandled rejections for the potential rejections that arrive after a short circuit. (I also want my PromiseAllOrRejections helper moved to endo to avoid writing code that causes unhandled rejections on short circuiting)
