Triggerlines for track reconstruction efficiency studies: add lines without UT and migrate to ThOr

relies on Rec merge request Rec!2669 (merged) and Phys merge request Phys!1031 (merged)

• DiMuonTrackEfficiency.py selects events with a tag and a probe track with the Tagging lines, and events where the probe machtes a long track with the Matching lines, for two different charges of the probe and for different lines. The new SeedMuon line as well as the VeloMuon line (formerly SciFiUT line) can be used in a detector without UT, while the Downstream line (formely Velo line) and MuonUT line (formely Long line) only return matched events if run with UT. They can be tested with hlt2_trackeff_test.py. This code was migrated from LoKi to ThOr.
• probe_muons.py, which calls hlt2_probetracks.py, is called by DiMuonTrackEfficiency.py to provide the probe and long tracks. Further methods for the new lines have been added.
• hlt2_noUT_trackeff_test.py is used to test the lines and create a dst file containing the information about events that passed either of the trigger lines. This doubles as a test for Rec!2669 (merged) and Phys!1031 (merged)
• test_hlt2_noUT_trackefflines.qmt is the relevant test
