bdc75a22d5 langgraph: expand handle_tool_errors in ToolNode (#1667 )

This change expands error-handling functionality of the `ToolNode` by
introducing more options for `handle_tool_errors`. Default behavior of
the `ToolNode` is unchanged -- all errors are handled and wrapped in a
`ToolMessage` to be sent back to LLM.

With this change, users have flexibility to only handle the exceptions
that they need to pass back to the LLM:

* they can specify exceptions to handle by passing a tuple of exceptions
in `handle_tool_errors`
* specify `handle_tool_errors=True/str/callable`
* when `handle_tool_errors` is a callable, the signature will be
inspected and exceptions from the signature will be handled
