call_tool decorator on the server side add the validate_output parameter

[tanhaipeng]

Description

Purpose

1. Allows the server to independently control whether to perform outputSchema validation (consistent with validate_input).
2. When both validate_input and validate_output are disabled, tool invocation skips _get_cached_tool_definition, thereby improving performance when calling call_tool.

Code demo

def call_tool(self, *, validate_input: bool = True, validate_output: bool = True):
      xxx

I will submit a PR, please help to merge it when I do.
