PureACL handles operators that generate no kernel (e.g. CONCATENATION) (#2437)

Related Issue: #2431

Dummy stage instance is added for `CONCATENATION` because Profiler assumes
every op inserts a stage.

The output will not show `CONCATENATION` slot because it is based on
runtime execution event. There was no event for `CONCATENATION` at runtime.
