Implement configuration function to customize MCP server

[KoolADE85]

This PR adds a function to configure the MCP server behaviour:

Rather than add a growing list of constructor args around the MCP server, this PR implements a single configure_mcp_server() function that allows users to toggle various parts of the server with arguments:

def configure_mcp_server(
    *,
    include_layout: bool = True,
    include_callbacks: bool = True,
    include_clientside_callbacks: bool = True,
    include_pages: bool = True,
    expose_callback_docstrings: bool = False,
) -> None:

The existing mcp_expose_docstrings constructor arg has been removed and replaced by this function.

I left a couple of suggestions, but nothing huge. Could you add a changelog entry for this update? Specifically describing the way the user facing API changed.

Suggested change

	self.mcp_callback_map: Any = None
	self.mcp_callback_map: Optional["CallbackAdapterCollection"] = None

[KoolADE85]

This is actually needs to be Any for now because of Python < 3.10.
CallbackAdapterCollection imports from the mcp module which cannot be installed on 3.8. Therefore, if we import it here for typing, it will break on older python versions.

Stupid backward compatibility!
