[PWGDQ] Add MC truth information and configurable tag

[dmallick2]

--Add Missing kMCMass map in VariableManger.cxx
--Fix some configurable tag options for read only truth level output on particular analysis , not store all lead to memory issue in dqEfficiency_withAssoc_direct.cxx
-- Add truth level histograms for PbPb in HistogramsLibrary.cxx
