[Feature Request] ensure responses are enabled for any enabled commands

[andy31415]

in project-chip/connectedhomeip#29509 we have found that one could configure commands such that the request for a command is code-generated, but not the response.

This seems odd:

• for servers, if you can process a request, being able to reply is mandatory
• for clients, if you can send a command presumably you have to be able to decode the reply

It seems reasonable to at a minimum show a large WARNING if such a mismatch happens and I believe it would be best to enforce that if a command is enabled, its response="..." is also enabled.
