HLT menu generation as part of common HLT configuration for upgrade tests
- Moves HLT menu generation into testHLT_MT.py (needed because L1Decoder needs the HLTMenu.json and hence it must be created)
- Makes LS2_v1 the default in testHLT_MT.py as only for this the new menu format is defined (pp_v8 as well)
- Disables new-style L1 menu generation for Physics_pp_v7 menu
- Makes GenerateMenuMT as singleton and memoizes generateMT() to avoid clashes from double execution of the menu generation (in the new jo system this will be handled by the accumulator)
