   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

   Original commit message:
   
       [promises] Change context promise hooks to Callable
   
       The previously added perf-context Promise-hooks take a v8::Function as
       arguments. However, the builtin code was only accepting JSFunctions
       which causes cast errors.
   
       Drive-by-fix: Directly pass nativeContext in more places.

   Original commit message:
   
       [runtime] Fix Promise.all context promise hooks
   
       We have to take the slow path in Promise.all if context promise hooks
       are set. The fast-path doesn't create intermediate promises by default.
