Fix false positive "Cannot capture" error reporting

There is no need to report an error in case of non-top-level
capture conversion, just don't add relevant capture type in the system instead

If system can be solved successfully without captured type, then it's just fine
(see KT-13950)
In case of contradiction TYPE_INFERENCE_PARAMETER_CONSTRAINT_ERROR is reported

 #KT-13950 Fixed
