feat(api): add CHECKBOX parameter type to plugin and tool entities

- Introduced CHECKBOX as a new parameter type in CommonParameterType and PluginParameterType.
- Updated as_normal_type and cast_parameter_value functions to handle CHECKBOX type.
- Enhanced ToolParameter class to include CHECKBOX for consistency across parameter types.
