Add the capability for api-fuzzer to fuzz over different config
variables, to enable us to spot incompatible configurations there
sooner.

Implement listeners, connection, endpoints for `FuzzingEventEngine`.
Allows the fuzzer to select write sizes and delays, connection delays,
and port assignments.
I made a few modifications to the test suite to admit this event engine
to pass the client & server tests:
1. the test factories return shared_ptr<> to admit us to return the same
event engine for both the oracle and the implementation - necessary
because FuzzingEventEngine forms a closed world of addresses & ports.
2. removed the WaitForSingleOwner calls - these seem unnecessary, and we
don't ask our users to do this - tested existing linux tests 1000x
across debug, asan, tsan with this change
Additionally, the event engine overrides the global port picker logic so
that port assignments are made by the fuzzer too.
This PR is a step along a longer journey, and has some outstanding
brethren PR's, and some follow-up work:
* #32603 will convert all the core e2e tests into a more malleable form
* we'll then use #32667 to turn all of these into fuzzers
* finally we'll integrate this into that work and turn all core e2e
tests into fuzzers over timer & callback reorderings and io
size/spacings

Return `Timeout(kMaxHours, Unit::kHours)` if the value is about to
overflow in `DivideRoundingUp`.

* Use a unique_ptr with custom deleter for grpc_transport in

* explicit release ownership
* Remove ResetDefaultEventEngine
Now that it is a weak_ptr, there's no need to explicitly reset it. When
the tracked shared_ptr is deleted, the weak_ptr will fail to lock, and a
new default EventEngine will be created.

* Reland x2: Make GetDefaultEventEngine return a shared_ptr
* remove thread leak from NativeDNSResolver
This is not going to work for resolvers that support cancellation.
* give resolvers bounded lifetimes
Some resolver own EventEngines. EventEngines cannot run off the end of
the process since they have unjoined threads (problematic in a small set
of environments). This gives resolvers bounded lifetimes, and allows
replacement of resolvers without ASAN issues of deleting resolvers in
active use (occurs in tests).
* fix
* fix windows
* fix surface init test
* fix
* sanitize
* use after move
* the test must wait for the callback to be destroyed
* windows fix: delete the resolver on iomgr shutdown, not before
* Make TimerManager threads non-joinable
On gRPC shutdown, any unjoined TimerManager threads will cause TSAN to
detect thread leaks. This fix resolves issues I saw in end2end test
shutdown in another PR, where a single timer manager thread was always
alive after the test ended.
The long-term solution is to integrate the new ThreadPool here, but this
unblocks me for now.
* backport fix
* fix
* shared_ptr<EventEngine> in EventEngine benchmarks
* Reland: "Make GetDefaultEventEngine return a shared_ptr (#30280)"
This reverts commit 45959e7cc1.
* Attempted fix with NoDestruct
* Not a process-wide singleton for the type. Just a NonDestruct
* fix
This works around valgrind memory leaks by giving EventEngines a fixed
lifetime. We eventually want ref-counted EventEngines internally, so this is
a step in the right direction as well.
* Rename the default EventEngine headers
Small cleanup. This code hasn't been related to factories for a month or
two.
* ensure only one target contains default_event_engine.h
* src + hdr in same target
* include guards
* Revert "Revert "Reland: Add SRV and TXT record lookup methods to the iomgr PAI (#30242)"
This reverts commit b5966f39eb.
* release lock before unreffing
* Revert "Reland: Add SRV and TXT record lookup methods to the iomgr API (#30206)"
This reverts commit c229703f9f.
* Automated change: Fix sanity tests
