Improvements in PEB/DS ART tests
The following changes are made:
- move the job options from TrigUpgradeTest (which is being phased out) to TrigP1Test
- use forceEnableAllChains to run the test chains regardless of L1 decision (fixes ATR-20829 and ATR-20830)
- move TrigBSDumpGrepStep from the timeout test to a separate python module
- add stream counting checks to the TrigP1Test PEB_DS test (using the TrigBSDumpGrepStep)
- minor fixes in the job options
