[FEAT]: Revamping the tools

[XuhuiZhou]

Description

The current tool in ToolEmu is inherited from their self-created FunctionTool

class FunctionTool(BaseTool):
    """
    Function tool is defined according to our specification that resembles Python function docstring, see `tool_interface.md`.
    """

    name: str = None
    summary: str = None
    parameters: List[ArgParameter] = None
    returns: List[ArgReturn] = None
    exceptions: List[ArgException] = None
    description: str = None

The ArgParameter, ArgReturn, and ArgException are essential Typedict, which could be error-prone and hard to verify.
e.g.,

class ArgException(TypedDict):
    """The exception for a tool"""

    name: str
    description: str

I am thinking of using a more elegant solution, basically, it would be good to turn ArgParameter, ArgReturn, and ArgException all into Pydantic structure so that we can easily verify the tool calling behavior of LLMs with Pydantic's internal verifier:

Please let me know what do you think! @frankxu2004 @ProKil @GloriaXimingLu @liweijiang
