Small redesign of jet chain dict keys
Small reorganization of the JetChainParts keys in SignatureDicts.py as discussed/proposed in ATR-22192.
'dataType' was separated into two new keys: 'constitType' and 'constitMod'.
'calib' was renamed to 'clusterCalib'
Some jet chains needed to be renamed due to those changes which is reflected by the changes on the reference files.
Trigger MET code needed to be slightly modified in order to correctly construct the jet dict. Tagging MET coordinators @bcarlson @jburr
