Add HMT and exclusive chains to Physics menu
This MR adds HMT chains (according to specification by @nova) and test exclusive chains. Minor fixes in the min bias codes were needed actually. Removes PS:Online from the other HMT/mb_sptrk chains to allow them to be tested in reprocessing(s) (they are still in lowMu group).
Addressed JIRAs: ATR-24396 and ATR-22830
