Add micro-benchmarks to verify the performance degradation related to
the number of active `AsyncLocalStorage`s.
With these benchmarks, trying to improve the async context propagation
to be an O(1) operation, which is an operation more frequent compared
to `asyncLocalStorage.run` and `asyncLocalStorage.getStore`.

Stack trace capturing currently accounts for 40 % of the benchmark
running time. Always throwing the same exception object removes
that overhead and lets the benchmark be more focused on what it is
supposed to measure.

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.

In the benchmark, because it performs asynchronous operations before
writing its HTTP replies, the underlying socket can be closed by the
peer before the response is written. Since 28e6626ce7, that means
that attempting to `.end()` the HTTP response results in an uncaught
exception, breaking the benchmark.
Fix that by checking whether the response object has been destroyed
or not before attempting to call `.end()`.

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.

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 adds a new `test` option. Using it automatically uses a single
minimal option matrix to verify the benchmark works as expected.
Using the new `all` option makes sure all test suites are run.
On top of that the benchmarks will from now on report properly
what category might have a typo, if any.
The http duration was also refactored to use a option instead of
relying on a configuration setting.
The fixture folder is ignored as test suite from now on.

In cases where libraries create AsyncResources which may be emitting
more events depending on usage, the only way to ensure that destroy is
called properly is by calling it when the resource gets garbage
