This should address one of the failures we're seeing in #34224.
The test failure is caused by the changes in timing triggering a race
condition. In the code at head, we delay sending out the subscription
for the first CDS watch until we've already seen the other two CDS
watches, because the previous send_message op has not yet completed, and
by the time it does, we've seen all 3 watches, so we can send a
subscription for all 3 at the same time. With the WorkSerializer change,
the send_message op is complete by the time we see the first CDS watch,
so we subscribe to only that resource, and then later add the other two.
The result is that we'll NACK twice with two different messages, the
first one including only the error about the first resource, and the
second one including all three.
I suspect this same race condition would have been triggered eventually
by the EventEngine migration anyway; the current test basically depends
on the single-thread timing of the iomgr approach. So I'm addressing it
by replacing the e2e test with a unit test that covers the same cases
without the timing issue.
Rolls forward part of the dualstack changes, mostly from #33427 and a
little bit from #32692, both of which were reverted in #33718.
Specifically:
- For petiole policies, unconditionally start health watch on
subchannels, even if client side health checking is not enabled; in this
case, the health watch will report the subchannel's raw connectivity
state.
- Fix edge cases in health check reporting that occur when a watcher is
started before the initial state is reported.
- When client-side health checking fails, add the subchannel's address
to the RPC failure status message.
- Outlier detection now works only via the health checking watch, not
via the raw connectivity state watch.
- Remove now-unnecessary hack to ensure that outlier detection does not
work for pick_first.
A new metadata type `x-envoy-peer-metadata` is being introduced. We
don't have a better way to do this at the moment compared to just adding
it in `metadata_batch.h`.
The GSM Observability plugin uses this metadata to send topology
information to peers in the form of serialized and base64 encoded
`google::protobuf::Struct`. The individual keys being used inside the
struct are subject to change.

If we get a readable event on an fd and both the following happens:
- c-ares does *not* read all bytes off the fd
- c-ares removes the fd from the set ARES_GETSOCK_READABLE
... then we have a busy loop here, where we'd keep asking c-ares to
process an fd that it no longer cares about.
This is indirectly related to a change in this code one month ago:
https://github.com/grpc/grpc/pull/33942 - before that change, c-ares
would close the socket when it called
[handle_error](7f3262312f/src/lib/ares_process.c (L707))
and so `IsFdStillReadableLocked` would start returning `false`, causing
us to get away with [this
loop](f6a994229e/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.cc (L371)).
Now, because `IsFdStillReadableLocked` will keep returning true (because
of our overridden `close` API), we'll loop forever.

We added this as an exploratory measure for a customer that thought they
were using open census (this turned out to be emphatically false).
Remove it since it's probably not how we ultimately want to do this, and
wait for something better to come along.

Update from gtcooke94:
This PR adds support to build gRPC and it's tests with OpenSSL3. There were some
hiccups with tests as the tests with openssl haven't been built or exercised in a
few months, so they needed some work to fix.
Right now I expect all test files to pass except the following:
- h2_ssl_cert_test
- ssl_transport_security_utils_test
I confirmed locally that these tests fail with OpenSSL 1.1.1 as well,
thus we are at least not introducing regressions. Thus, I've added compiler directives around these tests so they only build when using BoringSSL.

CNR the flake, but I've changed the test (which is very old) to use some
of our more modern helper functions that have saner timeouts.
Also re-add a `return` statement that was accidentally removed in
#33753, which I noticed while working on this. Its absence doesn't cause
a real problem, but it does cause us to needlessly trigger a duplicate
connection attempt or report a duplicate CONNECTING update in some
cases.
De-experiment pick first since we have both affinity and randomness E2E
test running successfully.

This PR is mainly a set of improvements that allow the C++ Alarm to be
migrated away from legacy iomgr. It cannot be landed without significant
speedup, due to third-parties relying on a fast path for immediate timer
execution with deadlines <= now.
Previous EventEngine performance of bm_alarm, compared to baseline iomgr
timers: *0.014%*
This PR: *2.5%*
Regarding previous failures to land this change: The cloud libraries
team agreed to reduce the amount of stress in their alarm stress test
https://github.com/googleapis/google-cloud-cpp/pull/12378
Fix sticky-TF behavior such that once we enter TRANSIENT_FAILURE, we do
not leave that state if we get a new address list.
Also, fix handling of subchannels in state TRANSIENT_FAILURE.
Previously, if a subchannel was already in state TRANSIENT_FAILURE when
we wanted to start a connection attempt on it (e.g., because the
subchannel already existed from a different channel, or because it
already existed in the previous subchannel list), we would wait for it
to report IDLE before attempting to connect. This PR changes pick_first
to instead immediately skip the subchannel and move on to the next one.
Now, the only time we wait for a subchannel in TRANSIENT_FAILURE is when
we wrap back around to the first subchannel in the list.
Port https://github.com/grpc/grpc/pull/33871 to EE's
GrpcPolledFdFactoryPosix.

We decided to not populate `policy_name` with the HTTP filter name in
xDS case. So removing it from `GenerateServiceConfig`. This will be
consistent across languages. The gRFC
[PR](https://github.com/grpc/proposal/pull/346) has been updated.

I'm fairly certain that this path should be non-blocking (and making it
so makes the promise based code far more tractable).
This moves the blocking behavior into the blocking server_cc.cc function
that calls `grpc_server_shutdown_and_notify` instead of in that
non-blocking function.
