The existing version of defaultTriggerAsyncIdScope creates an Array for the callback's arguments which is highly inefficient. Instead, use rest syntax and allow V8 to do that work for us. This yields roughly 2x performance for this particular function.

^ I doubt this will make a difference in that benchmark. It's a small speck within what it does. I just benchmarked the defaultTriggerAsyncIdScope function itself.

Here's an excerpt of those results:

@apapirovski you will be happy to know it is not a meaningless optimization:

This doesn't land cleanly on v9.x, should it be backported?

@MylesBorins This depends on #17273. I've backported that in #18079. If you land #18079 first then this lands cleanly.
