CP algorithms: rename the jvt selection name to something more explanatory

The selection name "jvt" introduced in JetAnalysisConfig has a slightly mis-leading name, because it may sound as if it only includes JVT decision, when in fact it can also pick up baseline selection (such as pT, eta cuts) and also overlap removal decision, if OR decision is set up to be appended to every jet selection.

Propose to rename the selection to baselineJvt to make it more clear for users that this bundles more than just JVT decision. Same reasoning for the fJVT.

Depends on !69110 (merged)
