Duplicate tests to check CA migration for Run3 TrigInDetValidation tests
As the title describes, this merge request adds copies of two Run3 tests in TrigInDetValidation to check the results after using the CA implementation of the RDOtoRDOTrigger step within the RDO -> AOD process. This comes from a thread in !68090 (merged), where the variable useCA_Reco was included so that the new Run4 tests use CA for the RDOtoRDOTrigger step, where we really want the Run3 tests migrated to use CA as well. This MR also moves flag settings specific for the Run4 tests to their corresponding test files, instead of being left and applied to the Run3 tests.
Checking locally on 100 events, the outputs of the CA and non-CA tests are the same. The first step in this migration is to test that there are no breaks when running on the full samples on the grid, and to compare results with the current non-CA version. Hence, only a couple of tests are duplicated - one which has specific pre-include file dependencies for non-CA (the tau test) now includes that specific configuration in preexec_trig, and the other test does not have any pre/post-include file dependancies (the ttbar test).
This has already been presented to and discussed with @sutt and @bkerridg.
