Improve consistency between jet trigger CA and legacy config

@cantel, @lbeemste, @jburr

Making progress erasing naming differences between the CA and legacy configs for jet chains

Notable changes:

• I put the jetDefStr into the jetRecoDict now, to make it easier to retrieve all over the code, without having to keep calling the function to construct it. The string is filled in on extraction of the dict from the chainParts.
• To help with keeping the name correct, I also added a copy-and-update function for the jetRecoDict used in e.g. grooming and reclustering workflows
• The JetViewAlg config is unified via the CA function + wrapper.
