Common trace levels?

Some DUNE-DAQ packages define descriptive constants for certain trace levels. Eg

https://github.com/DUNE-DAQ/readout/blob/develop/include/readout/ReadoutLogging.hpp

Some of these descriptive constants are duplicated in multiple packages. It might be worth putting these common constants in a single place.

Here's a list of constant/filename I made from the packages that are part of the 2.6 release. The repeated constants would be the candidates for inclusion in a common list:

 TLVL_BASIC: dfmodules/plugins/HDF5DataStore.hpp

Start by comparing the repeated trace-level constants in logging/detail/Logger.hxx, readout/include/readout/ReadoutLogging.hpp, trigger/include/trigger/Issues.hpp, and the other listed files. Determine which constants are genuinely common and where a shared definition belongs. Done means the agreed common constants are centralized without duplicated definitions across the listed packages.
