Run3 trig feature access test7
Introduced Run3 access to jets and PV's in the Run2 legacy code.
The code was tested on a file with Run2 access and on a file with Run3 access, generated with the standard test_trigAna_q221_RDOtoAOD_build.sh and test_trigAna_q221_RDOtoAOD_mt1_build.sh macros, respectively.
This update is an essential part of the program outlined in ATR-19881, ATR-20006 and ATR-19453.
