* 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)"

* Rename ResolveName to LookupHostname (same as EventEngine)
* Add stubs and no-op impls for LookupTXT and LookupSRV
* add native resolver tests that assert unimplemented
* extract custom name_server-setting logic and remove goto
* Separate SRV queries from grpc_dns_lookup_ares

* Automated change: Fix sanity tests
* fix missing ExecCtx on resolver tests
* separate out TXT lookup from hostname lookup (now all 3 are separate)
* rm DNS and update docs
* fix the fixer (forgot to add deps to BUILD)
* remove unused SRV and TXT args from ares hostname lookup method
* rename hostname-only ares dns lookup method
* refactor AresRequest using template method pattern
* Add name_server to Ares LookupHostname internals (needs iomgr API change)

Used a custom bind server with some redacted tests from
`resolve_address_test` to ensure both are working as expected.

DNS requests were previously cancellable, but it was assumed
that the resolution callback would be called in all cases. Now, requests
provide a `bool Cancel(TaskHandle handle)` method that lets callers know
whether cancellation is successful, and if so, the callback will not be
run.
This is in accordance with EventEngine's cancellation semantics, and it
is a step towards migration from iomgr to EventEngine.
* Support unix socket in grpc_sockaddr_to_string

* Let Chttp2ServerListener::Start crash
* test failure fixed
* api_fuzzer fixed
* comments addressed.
* more comments addressed

* reviewer feedback
* first pass at excluding EventEngine test expansion
Also caught a few cases where we should not test pollers, but should
test all engines. And two cases where we likely shouldn't be testing
either product.
* end2end fuzzers to be fuzzed differently via EventEngine.
* sanitize
* reviewer feedback
* remove misleading comment
* reviewer feedback: comments
* EE test_init needs to play with our build system
