Nuno Campos a9aa3f232d feat(langchain_v1): Add retry_model_request middleware hook, add ModelFallbackMiddleware (#33275 )

- retry_model_request hook lets a middleware decide to retry a failed
model request, with full ability to modify as much or as little of the
request before doing so
- ModelFallbackMiddleware tries each fallback model in order, until one
is successful, or fallback list is exhausted
