Convert PseudoJetGetters to algs
Converted PseudoJetGetter and MuonSegmentPseudoJetGetter into PseudoJetAlgorithms, eliminating all other specialised PseudoJetGetters with the exception of the trigger versions, which are used in the legacy jet trigger reconstruction.
WIP while I work on the python configuration in the RecExCommon style jobOptions that are still used for offline reco.
This is an update of !32775 (closed), and I still need to pull over the JetIsolationTool change from that one. It addresses ATLJETMET-1248.
