Use class hierarchy to organize AgentChat message types and introduce StructuredMessage type (#5998)
This PR refactored `AgentEvent` and `ChatMessage` union types to
abstract base classes. This allows for user-defined message types that
subclass one of the base classes to be used in AgentChat.

To support a unified interface for working with the messages, the base
classes added abstract methods for:
- Convert content to string
- Convert content to a `UserMessage` for model client
- Convert content for rendering in console.
- Dump into a dictionary
- Load and create a new instance from a dictionary

This way, all agents such as `AssistantAgent` and `SocietyOfMindAgent`
can utilize the unified interface to work with any built-in and
user-defined message type.

This PR also introduces a new message type, `StructuredMessage` for
AgentChat (Resolves #5131), which is a generic type that requires a
user-specified content type.

You can create a `StructuredMessage` as follow:

```python

class MessageType(BaseModel):
  data: str
  references: List[str]

message = StructuredMessage[MessageType](content=MessageType(data="data", references=["a", "b"]), source="user")

# message.content is of type `MessageType`. 
```

This PR addresses the receving side of this message type. To produce
this message type from `AssistantAgent`, the work continue in #5934.

Added unit tests to verify this message type works with agents and
teams.

Building the AutoGen Documentation

AutoGen documentation is based on the sphinx documentation system and uses the myst-parser to render markdown files. It uses the pydata-sphinx-theme to style the documentation.

Prerequisites

Ensure you have all of the dev dependencies for the autogen-core package installed. You can install them by running the following command from the root of the python repository:

uv sync
source .venv/bin/activate

Building Docs

To build the documentation, run the following command from the root of the python repository:

poe --directory ./packages/autogen-core/ docs-build

To serve the documentation locally, run the following command from the root of the python repository:

poe --directory ./packages/autogen-core/ docs-serve

[!NOTE] Sphinx will only rebuild files that have changed since the last build. If you want to force a full rebuild, you can delete the ./packages/autogen-core/docs/build directory before running the docs-build command.

Versioning the Documentation

The current theme - pydata-sphinx-theme - supports switching between versions of the documentation.

To version the documentation, you need to create a new version of the documentation by copying the existing documentation to a new directory with the version number. For example, to create a new version of the documentation for version 0.1.0, you would run the following command:

How are various versions built? - TBD.
