* perf: Remove expensive reflection from raft/mesh hot path
Replaces a reflection-based copy of a struct in the mesh topology with a
deep-copy generated implementation.
This is in the hot-path of raft FSM updates, and the reflection overhead was a
substantial part of mesh registration times (~90%). This could manifest as raft
thread saturation, and resulting instability.

This will likely happen frequently with sameness groups. Relaxing this
constraint is harmless for failover because xds/endpoints exludes cross
partition and peer endpoints.

Fix ACL check on health endpoint
Prior to this change, the service health API would not explicitly return an
error whenever a token with invalid permissions was given, and it would instead
return empty results. With this change, a "Permission denied" error is returned
whenever data is queried. This is done to better support the agent cache, which
performs a fetch backoff sleep whenever ACL errors are encountered. Affected
endpoints are: `/v1/health/connect/` and `/v1/health/ingress/`.
* Fix namespaced peer service updates / deletes.
This change fixes a function so that namespaced services are
correctly queried when handling updates / deletes. Prior to this
change, some peered services would not correctly be un-exported.
* Add changelog.
To avoid unintended tampering with remote downstreams via service
config, refactor BasicEnvoyExtender and RuntimeConfig to disallow
typical Envoy extensions from being applied to non-local proxies.
Continue to allow this behavior for AWS Lambda and the read-only
Validate builtin extensions.
Addresses CVE-2023-2816.

* Modify getReadyUpstreams to filter upstreams by listener (#17410)
Each listener would previously have all upstreams from any route that bound to the listener. This is problematic when a route bound to one listener also binds to other listeners and so includes upstreams for multiple listeners. The list for a given listener would then wind up including upstreams for other listeners.

This change enables workflows where you are reapplying a resource that should have an owner ref to publish modifications to the resources data without performing a read to figure out the current owner resource incarnations UID.
Basically we want workflows similar to `kubectl apply` or `consul config write` to be able to work seamlessly even for owned resources.
In these cases the users intention is to have the resource owned by the “current” incarnation of the owner resource.
