This patch adds the OpenLab CI configuration to enable
the support for Envoy arm64 build in OpenLab.

After this, each pull request in envoy will trigger the
envoy-arm64-build job which verified the arm build
on OpenLab ARM cluster.

For posterity #6875 got us the information it was a "waiting for stats" bug, which is then debuggable by lowering load stats interval to 1ms.

This exposed two issues with merge. When request 1 arrived in a separate interval from request 2, the stats protos could arrive in the opposite order (fixed by ignoring order) and that if there was a stats-update with a request in progress it never resolved because we were always adding fields (oops!)

I'm tempted to leave the interval low now that this is thoroughly debugged, but there's expectations on the time being within a range which wouldn't work if we lower it so meh?

This is due to the race described by envoyproxy#22855. Making sure the dispatcher thread is running before starting the test avoids this problem.

This test sends a large number of metadata frames in order to trigger a disconnect. However, it was possible for the disconnect to happen and the connection to be torn down before all the metadata frames had been sent. If that happened, ASAN detected a UAF:

…yproxy#35410)

When the ``AsyncTcpClient`` is being destroyed but it
also has an active client connection, there's a crash since during the
instance destruction, the ``ClientConnection`` object would also be
destroyed, causing ``raiseEvent`` to be called back to
``AsyncTcpClient`` while it is being destroyed

Caught with the following stack trace:
```

Commit Message: Add stacktrace to ASSERTs
Additional Description: Before this change, ASSERTs provoke a
stacktrace, but it is always the useless two-line stacktrace
```
#0: sigHandler()
#1: restore_rt
```
as demonstrated by the test case added in this PR not passing before the
change.
It's a bit odd that after this change there will be two stacktraces
output on assert, but at least one of them will be useful.

Risk Level: Minimal, it's just output from asserts so if it does
anything it's during a crash anyway.
Testing: Added a test case, and used to debug my production issue which
I couldn't with the original version.

NOTE: libFuzzer has rudimentary signal handlers.
      Combine libFuzzer with AddressSanitizer or similar for better crash reports.
SUMMARY: libFuzzer: deadly signal

This PR adds a linking flag to allow the fuzzers to properly handle
exceptions.

## Description

Today, when a filesystem watch callback returns a non-OK status or
throws an exception, the error gets propagated to `FileEventImpl` which
uses `THROW_IF_NOT_OK`.

Since there's no exception handler in the `libevent` loop, this causes
`std::terminate` to be called, which crashes Envoy.

**Stack Trace:**

```

In this change, we are making the `inotify` and `kqueue` watchers handle
callback errors gracefully by catching any exceptions using
`TRY_ASSERT_MAIN_THREAD`, logging errors instead of propagating them and
always returning the `OkStatus` to the event loop.

error or throws
**Additional Description:** Make `inotify` and `kqueue` watchers handle
callback errors gracefully.

Commit Message:
The LEDS subscription callback lambda captured `used_load_assignment` by
value as a raw pointer to the object owned by the
`cluster_load_assignment_` unique_ptr. When a subsequent EDS update
reassigned `cluster_load_assignment_`, the old object was destroyed but
existing LEDS subscriptions (not recreated for unchanged configs) still
held the dangling pointer. When the LEDS subscription later fired its
callback (e.g. onConfigUpdateFailed), dereferencing this pointer caused
a segfault.

Stack trace:

Fix by capturing `this` and accessing `cluster_load_assignment_`
directly, which always reflects the current valid assignment.
