[Feature Request] Add support for separate input/output schemas

[dotsbb]

New Feature - add an ability to maintain separate schemas for request and response models, similar to FastAPI's implementation.

Current Behavior

Currently, parse_parameters overwrites component schemas (APIView.components_schemas) that were previously extracted by get_responses. Usually get_responses returns different schemas due tomode="serialization" and we're loosing any additional information (such as @computed_fields)

Proposed Solution

I could add a new configuration option separate_input_output_schemas:

• Defaults to false to maintain backward compatibility
• When enabled, maintains distinct schemas for:
  • Request bodies and parameters -Input suffix
  • Response models -Output suffix

@luolingchun What are your thoughts on this? If you feel this feature would be valuable, I can begin implementation next week. Please share any context or feedback that would help inform the work.
