Make shared session possible for MCP tool (#6312 )

Resolves #6232, #6198

This PR introduces an optional parameter `session` to `mcp_server_tools`
to support reuse of the same session.

```python
import asyncio

from autogen_agentchat.agents import AssistantAgent
from autogen_agentchat.conditions import TextMentionTermination
from autogen_agentchat.teams import RoundRobinGroupChat
from autogen_agentchat.ui import Console
from autogen_ext.models.openai import OpenAIChatCompletionClient
from autogen_ext.tools.mcp import StdioServerParams, create_mcp_server_session, mcp_server_tools


async def main() -> None:
    model_client = OpenAIChatCompletionClient(model="gpt-4o", parallel_tool_calls=False)  # type: ignore
    params = StdioServerParams(
        command="npx",
        args=["@playwright/mcp@latest"],
        read_timeout_seconds=60,
    )
    async with create_mcp_server_session(params) as session:
        await session.initialize()
        tools = await mcp_server_tools(server_params=params, session=session)
        print(f"Tools: {[tool.name for tool in tools]}")

        agent = AssistantAgent(
            name="Assistant",
            model_client=model_client,
            tools=tools,  # type: ignore
        )

        termination = TextMentionTermination("TERMINATE")
        team = RoundRobinGroupChat([agent], termination_condition=termination)
        await Console(
            team.run_stream(
                task="Go to https://ekzhu.com/, visit the first link in the page, then tell me about the linked page."
            )
        )


asyncio.run(main())
``` 

Based on discussion in this thread: #6284, we will consider
serialization and deserialization of MCP server tools when used in this
manner in a separate issue.

This PR also replaces the `json_schema_to_pydantic` dependency with
built-in utils.
