Specify failure_error_function for mcp tool

[sandsc]

When create a function tool via @function_tool, a failure_error_function can be passed to process tool invoke exception. However, invoke_mcp_tool in util.py always raise an exception when tool invoke crashed.

Is it possible to specify a failure_error_function for the execution of the MCP Tool?
