refactor(core): ai input (#11381)

Close [BS-2758](https://linear.app/affine-design/issue/BS-2758).
Support [BS-2583](https://linear.app/affine-design/issue/BS-2583).

### What changed?
- Extend `ChatPanelInput` and `ChatBlockInput` from the same abstract class `AIChatInput` to reduce duplication of code.
- Unify the context interface of `chat-panel` and `chat-block`.
  - Rename `items` field to `messages`.
  - Remove duplicated type declare.
