Dropped compilation of DetDesc in DD4hep mode and adapted code

This includes :

• a cleanup of the TransportSvc interface
  • dropped old non reentrant methods
  • renamed reentrant methods withour "_r"
  • return intersections in intersections methods, rather than relying on filling a vector passed by reference (and cleaning it first)
  • removed unused entry points
• usage of dd4hep Material through the wrapper Detector::Material
  • provides the same interface as DetDesc
  • but is a Handle and not a pointer, hence a bunch of ifdefs in key places
• dropping a lot of unused code/classes :
  • OfflineRateLimiter, RateFromCondDB
  • HltEvaluator, HltRoutingBitsWriter
  • HCRawBankDecoderHlt
  • RunChangeHandle
  • PreloadGeometryTool
• dropping usage of UpdateManagerSvc in MDFReadingExample.py so that it's DD4hep compatible
• dropping unused writeToXML feature of IUTReadoutTool
• dropping unused hlt2 mode in HltConfigSvc
• adding veloisClosed method to DeVP
• merging RateFromTCK into GetLumiParameter
• modernizing RateFromTCK (and made it DD4hep compliant)
• fixing scope of compilation for Det/Magnet in DD4hep mode
