src: set PromiseHooks by Environment
The new JS PromiseHooks introduced in the referenced PR are per
v8::Context. This meant that code depending on them, such as
AsyncLocalStorage, wouldn't behave correctly across vm.Context
instances.

PromiseHooks are now synchronized across the main Context and any
Context created via vm.Context.
