- Communicate the current async stack length through a
typed array field rather than a native binding method
- Add a new fixed-size `async_ids_fast_stack` typed array
that contains the async ID stack up to a fixed limit.
This increases performance noticeably, since most of the time
the async ID stack will not be more than a handful of
levels deep.
- Make the JS `pushAsyncIds()` and `popAsyncIds()` functions
do the same thing as the native ones if the fast path
is applicable.

SetupHooks is only available via `process.binding('async_wrap')`, so
there's no reason it shouldn't be called with the appropriate arguments,
since it is an internal-only function. The only place this function is
used is `lib/internal/async_hooks.js`.

Previously the getter would mutate the kDefaultTriggerAsncId value. This
refactor changes the setter to bind the current kDefaultTriggerAsncId to
a scope, such that the getter doesn't have to mutate its own value.

rename initTriggerId to defaultTriggerAsyncId such it matches the rest
of our naming.

At its call sites, `ClearFatalExceptionHandlers()` was used to
make the process crash as soon as possible once an exception occurred,
without giving JS land a chance to interfere.
`ClearFatalExceptionHandlers()` awkwardly removed the current domain
and any `uncaughtException` handlers, whereas a clearer way is to
execute the relevant reporting (and `exit()`) code directly.

async_hooks emits trace_events. This adds the executionAsyncId to the
init events. In theory this could be inferred from the before and after
events but this is much simpler and doesn't require knowledge of all
events.
