  1. async_hooks: optimize fast-path promise hook for ALS 

    Remove unnecessary native-to-JS code switches in fast-path for
PromiseHooks. Those switches happen even if a certain type of
hook (say, before) is not installed, which may lead to sub-optimal
performance in the AsyncLocalStorage scenario, i.e. when there is
only an init hook.
