Fixed the issue where AnyLLMModel failed to verify ResponsesParams when calling multiple rounds of tools.
Root cause: Some versions of any-llm's ResponsesParams.input field only accepts str,
However, after multiple rounds of dialogue, input is already list[TResponseInputItem], causing pydantic to report a verification error.
Fix: Override _make_any_llm_responses_params to force the use of the built-in shim class,
Bypassing pydantic verification, the payload is directly transparently transmitted.
