Support tools calling

Going to work on this during DDD25

@jibla: it turns out that function calling is not yet supported by google-gemini-php. There is a PR https://github.com/google-gemini-php/client/pull/67 against beta branch, but not merged yet.

Should we park the issue until PR is merged, or switch to vanilla Guzzle requests as suggested in related Google Vertex issue https://www.drupal.org/project/ai_provider_google_vertex/issues/3506263 🐛 Vertex provider uses PredictionServiceClient and slows down response time. Active ?

Heads up: https://github.com/google-gemini-php/client/pull/92 is merged into main

@valthebald exactly! :) I will take care of it, this week

Any updates on this? This module still doesn't work with AI 1.1.0.

@balazswmann technically, it does, but you can't use gemini as a chat with tools.
@jibla do you need some help with that?

@valthebald

Yes, I meant the chat and tools compatibility. That's exactly I'd need.

@valthebald
Actually if somebody from the community would suggest a MR, it would help. Otherwise I will try to push this in my team.
