fix: streamline management of user-selected produces and consumes values (#4137)

* Remove produces/consumes setter from OperationContainer

* Store consumes/produces information in `meta` key

* Migrate produces value state usage to `meta` key

* use meta consumes data for isXml check

* Fix failing tests

* normalize action name casing

* restore correct produces fallback value logic
