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.
