This avoids the need to wrap every promise in an AsyncWrap and also
makes it easier to skip the machinery to track destroy events when
there's no destroy listener.

In the worker pool example, the 'kWorkerFreedEvent' should be emitted
in case of error as well. After adding new worker in the error handler,
the pending tasks should be notified of an available worker.

This allows transitioning the entire following sync and async execution
sub-tree to the given async storage context. With this one can be sure
the context binding will remain for any following sync activity and all
descending async execution whereas the `run*(...)` methods must wrap
everything that is intended to exist within the context. This is helpful
for scenarios such as prepending a `'connection'` event to an http
server which binds everything that occurs within each request to
the given context. This is helpful for APMs to minimize the need
for patching and especially adding closures.

This commit introduces store as the first argument in
AsyncLocalStorage's run methods. The change is motivated by the
following expectation: most users are going to use a custom object
as the store and an extra Map created by the previous implementation
is an overhead for their use case.
Important note. This is a backwards incompatible change.
It was discussed and agreed an incompatible change is ok
since the API is still experimental and the modified
methods were only added within the last week so usage
will be minimal to none.

This seems to have been overlooked in commit b605b15346 ("async_hooks:

It is documented elsewhere in the async_hooks API documentation, except
where you actually pass it in.
