Add FunctionCallIndex to ConvertCliToOpenAIParams and enhance tool call handling

- Introduced `FunctionCallIndex` to track and manage function call indices within `ConvertCliToOpenAIParams`.
- Enhanced handling for `response.completed` and `response.output_item.done` data types to support tool call scenarios.
- Improved logic for restoring original tool names and setting function arguments during response parsing.
