TrigUpgradeTest: Code reorganziation
This MR replaces !35131 (closed). The code changes have already been review-approved, i.e.:
- TUT source code to DecisionHandling
- emu_step_* tests to DecisionHandling: as unit tests
- full_menu_cf test to TriggerMenuMT: as configuration only
Related to ATR-21713.
In addition this MR here disables the set of "emu_step" menu tests that are failing (ATR-21840).
