Original commit message:
Reland "[api] JSFunction PromiseHook for v8::Context"
This is a reland of d5457f5fb7ea05ca05a697599ffa50d35c1ae3c7
after a speculative revert.
Additionally it fixes an issue with throwing promise hooks.
Original change's description:
> [api] JSFunction PromiseHook for v8::Context
>
> This will enable Node.js to get much better performance from async_hooks
> as currently PromiseHook delegates to C++ for the hook function and then
> Node.js delegates it right back to JavaScript, introducing several
> unnecessary barrier hops in code that gets called very, very frequently
> in modern, promise-heavy applications.
>
> This API mirrors the form of the original C++ function based PromiseHook
> API, however it is intentionally separate to allow it to use JSFunctions
> triggered within generated code to, as much as possible, avoid entering
> runtime functions entirely.
>
> Because PromiseHook has internal use also, beyond just the Node.js use,
> I have opted to leave the existing API intact and keep this separate to
> avoid conflicting with any possible behaviour expectations of other API
> users.
>
> The design ideas for this new API stemmed from discussion with some V8
> team members at a previous Node.js Diagnostics Summit hosted by Google
> in Munich, and the relevant documentation of the discussion can be found
> here: https://docs.google.com/document/d/1g8OrG5lMIUhRn1zbkutgY83MiTSMx-0NHDs8Bf-nXxM/edit#heading=h.w1bavzz80l1e
