feat: support doubao seed 2.0 models (#12929)

### What this PR does

Before this PR:
- No support for Doubao Seed 2.0 models or their function-calling
capabilities.
-
https://console.volcengine.com/ark/region:ark+cn-beijing/model/detail?Id=doubao-seed-2-0-pro

After this PR:
- Adds support for Doubao Seed 2.0 models.
- Adds function-calling、vision support for Doubao Seed 2.0 models.

Fixes #

### Why we need it and why it was done in this way

The following tradeoffs were made:
- Implemented explicit support to enable new model features while
maintaining existing model paths.

The following alternatives were considered:
- Delay model-specific support until a unified model interface is
available.

Links to places where the discussion took place: <!-- optional: slack,
other GH issue, mailinglist, ... -->

### Breaking changes

- None anticipated.

### Special notes for your reviewer

- Verify integration and function-calling behavior with Doubao Seed 2.0
endpoints.

### Checklist

- [ ] PR: The PR description is expressive enough and will help future
contributors
- [ ] Code: Write code that humans can understand and keep it simple
- [ ] Refactor: Left the code cleaner than found
- [ ] Upgrade: Impact on upgrade flows considered if required
- [ ] Documentation: User-guide update considered

Release note
