fix(openai): Simplify Responses input handling

[alexander-alderman-webb]

Description

• Do not handle parameters which are not declared for Responses.create.
• Stop checking for sentinel values when setting the request model, because the model is required.
• Replace set_data_normalized with set_data for parameters declared to have primitive types.
