fix: Add support for Gemini internal tools in tool formatting

- Add explicit handling for Gemini internal tools (googleSearch, urlContext, codeExecution) in both _format_tools_for_litellm() and format_tools() methods
- Update docstrings to document new capability
- Resolves issue where Gemini internal tools were skipped with ''unsupported type'' error
- Maintains backward compatibility with existing tool formats
- Fixes #919
