Fixing FTF trigger test for ITk
Fixes ATR-28272
This request gets test_trig_mc_newJO_ITK_build (FTF with ITk trigger test) working once again.
This test was failing due to the migration to CA meaning that the config TrigFastTrackFinderCfg from TrigFastTrackFinder/TrigFastTrackFinderConfig was being used for some signatures instead of TrigInDetConfig/TrigInDetConfigITk which was previously used for the test. However, the implementation inside TrigFastTrackFinderConfig is for run 3 only. The changes outlined in this MR enables the trigger to run FTF with ITk taking advantage of the existing run 3 CA infrastructure, meaning that TrigInDetConfigITk is no longer needed. The changes include using ITk specific configurations, and in some cases making ITk-trigger specific configs. This test uses a run 4 single muon RDO, so we only enable the muon signature. We are intending on also making a ttbar + 200 pileup version of this test as well, which will use the full menu (or as much as possible).
