Add new Trigger DB lookups for Run3

Add new DB lookups for the Run3 Trigger DB's (ATR-19384)

Have added _Run2 lookups too for guidance, but have not moved the general lookups to the Run3 DB's to avoid conflicts when we want to read Run2 information in master.

Changes are minimal and as have done before, but noticed while testing compiling I can't get the correct cmake setup as get error:
The required authentication file /cvmfs/atlas-nightlies.cern.ch/repo/sw/master_Athena_x86_64-centos7-gcc8-opt/atlas/offline/external/AtlasAuth/v21/authentication.xml does not exist!

which should be pointing to the new file:
/afs/cern.ch/atlas/offline/external/AtlasAuth/v21/authentication.xml

Tested by linking that file inside /build/x86_64-centos7-gcc8-opt/XML/AtlasAuthentication after running make and confirm I can connect to the empty DB so the changes are working
