fix(router): don't cool down parent deployment on advisor sub-call failure (#33792)
* fix(router): don't cool down parent deployment on advisor sub-call failure

Advisor orchestration issues a sub-call to a different provider/credentials than the selected deployment. When that sub-call fails (e.g. a 401 because no advisor API key is configured), the exception propagates up and the router's deployment_callback_on_failure attributes it to the healthy parent deployment's model_info.id, cooling it down and rejecting unrelated callers to the same model group.

Tag advisor sub-call failures on the exception and skip cooldown for them in deployment_callback_on_failure. The exception is tagged rather than wrapped so its type is preserved and retry/fallback classification and the client-facing error are unchanged. Genuine executor/deployment failures are untagged and still cool down as before.

* refactor(router): tag advisor orchestration failures via provider-neutral util

Address review on LIT-4565: move the cooldown-exemption marker into
litellm/router_utils/cooldown_handlers.py so the router imports it at
module top instead of an in-function anthropic import, and extend the
exemption to AdvisorMaxIterationsError so a max-iterations orchestration
failure no longer cools down the healthy executor deployment.
