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.

generally don't want to benchmark deprecated things by default anyway.
Remove the deprecated value from the default list. Bonus is that this
will speed up the benchmark.

So far the benchmarks created a highly specialized function which
would inline exactly to the input. This changes it to provide a
more realistic view to actual input by changing the input on each
iteration. That prevents the function to be to specific.
It also reduces the number of iterations the benchmarks are run to
reduce the overall runtime. A microbenchmark should already show a
significant difference with lower iterations, otherwise the
significance for real world applications is only limited.
