TrigUpgradeTest: new config-only test and minor exec improvements
Adding new test running config-only with full_menu_cf.py job opts (ATR-20059).
Also making a few minor improvements in TUT exec scripts:
- allow specifying extra ATHENAOPTS
- make perfmon run by default as it was intended
- don't print checkFile and checkxAOD output to stdout, only to file
- redirect perfmon.py output to log
