Warn when a non-existent property of an unfinished module.exports
object is being accessed, as that very often indicates the presence
of a hard-to-detect and hard-to-debug problem.
This mechanism is only used if `module.exports` is still a
regular object at the point at which the second, circular `require()`
happens.
The downside is that, temporarily, `module.exports` will have a
prototype other than `Object.prototype`, and that there may
be valid uses of accessing non-existent properties of unfinished
`module.exports` objects.
Performance of circular require calls in general is not
noticeably impacted.

Since worker threads are complete Node.js environments, including the
ability to load native addons, and since those native addons can
allocate resources to be freed when objects go out of scope, and since,
upon worker thread exit, the engine does not invoke the weak callbacks
responsible for freeing resources which still have references, this
modification introduces tracking for weak references such that a list
of outstanding weak references is maintained. This list is traversed
during environment teardown. The callbacks for the remaining weak
references are called.
This change is also relevant for Node.js embedder scenarios, because in
those cases the process also outlives the `node::Environment` and
therefore weak callbacks should also be rendered as environment cleanup
hooks to ensure proper cleanup after native addons. This changes
introduces the means by which this can be accomplished.
A benchmark is included which measures the time it takes to execute the
weak reference callback for a given number of weak references.

This improves dgram performance by avoiding unnecessary async
operations.
One issue with this commit is that it seems hard to actually create
conditions under which the fallback path to the async case is
actually taken, for all supported OS, so an internal CLI option
is used for testing that path.
Another caveat is that the lack of an async operation means
that there are slight timing differences (essentially `nextTick()`
rather than `setImmediate()` for the send callback).

Many benchmarks use test/common/tmpdir. This changes 3 benchmarks that
use NODE_TMPDIR to also use test/common/tmpdir.
This is necessary in preparation for the next commit that changes tmpdir
to delete tmpdir.path when the Node.js process exits. Thus, if multiple
benchmarks are run sequentially, the ones that use tmpdir will remove
the directory and the ones changed here would fail because it does not
exist. This happens when running test/benchmark.
Note: to explicitly select a directory for tmpdir, use NODE_TEST_DIR.

Fix some issues introduced/not fixed via
https://github.com/nodejs/node/pull/25094:
* Init hook is not emitted for a reused HTTPParser
* HTTPParser was still used as resource in init hook
* type used in init hook was always HTTPINCOMINGMESSAGE even for client
requests
* some tests have not been adapted to new resource names
With this change the async hooks init event is emitted during a call
to Initialize() as the type and resource object is available at this
time. As a result Initialize() must be called now which could be seen
as breaking change even HTTPParser is not part of documented API.
It was needed to put the ClientRequest instance into a wrapper object
instead passing it directly as async resource otherwise
test-domain-multi fails. I think this is because adding an EventEmitter
to a Domain adds a property 'domain' and the presence of this changes
the context propagation in domains.
Besides that tests still refering to resource HTTPParser have been
updated/improved.
