Add transient xAOD::EventInfo in EVNT-to-EVNT workflows and enable EventInfoTag

Merge request !43471 (merged) disabled the addition of the EventInfoTag structure in EVNT files produced in EVNT-to-EVNT workflows. The reason being that building EventInfoTag broke the transform because the responsible tool requires a read handle for xAOD::EventInfo, which was not available. We would like EventInfoTag to allow selective reading of events.

This MR adds the algorithm creating an xAOD::EventInfo from the legacy event info to that workflow. To ensure the event store content of the resulting files is unchanged the xAOD::EventInfo is specifically not added to the items in the output stream. This makes the required xAOD::EventInfo available for the generation of EventInfoTag, without changing downstream content.
