Unifying new-style LAr config for Digi & Reco.
- Put LArACD2MeVCondAlgCfg into LArRecUtilsConfig
- Explicitly declare all conditions data required by each component (instead of wholesale import-everything)
- Switch unit-tests to RDO-input. Many tools in LArRecUtils are simulation-only.
- Delete flags and such copied over from the old configuration but last active usage pre-dates data-taking.
