TrigInDetValidation ART tests move to new steering

• Implement new steering for all ART tests.

• Save previous tests, renamed with an _old suffix. Remove any _new suffixes.

• Rename: TrigInDetNewArtSteps.py -> TrigInDetArtSteps.py -> TrigInDetOldArtSteps.py

• Rename: TrigInDetValidation_NewBase.py -> TrigInDetValidation_Base.py -> TrigInDetValidation_OldBase.py

• Fix larged0 tests' TIDArdict commands to use larged0 cuts/binning added to TrigInDetAnalysisUser/share:

    test/test_trigID_el_singlee_7-80_larged0.py
    test/test_trigID_el_singlee_7-80_larged0_pu.py
    test/test_trigID_mu_singlemu_larged0.py
    test/test_trigID_mu_singlemu_larged0_pu.py

• Add vertexing plots for:

    test/test_trigID_fsjet_pu40_st
    test/test_trigID_fsjet_ml_pu40

• Add -r Offline to offline TIDArdict commands for:

    test/test_trigID_all_ttbar_pu40
    test/test_trigID_fsjet_pu40
    test/test_trigID_fsjet_nopps_pu40
    test/test_trigID_tau_ztautau_pu46

• Remove old test

    test/test_trigID_mu_zmumu_pu40_mt-old

• Added -t option for all test scripts. This performs a dry run to test the configuration.

Note for reviewers: this MR renames quite a few files that GitLab doesn't seem to recognise as renames. So the changes aren't quite as extensive as it might seem. Also, all changes are in ART test scripts (Python and data files), so won't affect release build.
