Add support for custom tools that return plain text instead of JSON in the Response API.

Changes:
- Add CustomTool struct and .custom case to Tool enum
- Add CustomToolCall struct and .customToolCall case to OutputItem enum
- Add CustomToolChoice struct and .customTool case to ToolChoiceMode enum

Custom tools enable models to return plain text responses without JSON wrapping,
useful for scenarios like code execution, mathematical expressions, or structured
text outputs.

Note: CustomToolCallOutput was intentionally not included as it is not documented
in the OpenAI API documentation for multi-turn conversations with custom tools.
