Monotonic.h:112:19: error: 'exchange' is not a member of 'std' with gcc 12

Hello @clemenci, we are building LCG stack with gcc 12 and we are getting a compilation error. It seems that #include <utility> is missing from https://gitlab.cern.ch/gaudi/Gaudi/-/blob/master/GaudiKernel/include/Gaudi/Arena/Monotonic.h

Could you please have a look? I am attaching full build log as well.Gaudi-master-build.log
