LCW calibrations for topoclusters
Create a separate algorithm to shallow copy and calibrate topoclusters (rather than running the topoclustering twice - once for EM and once for LCW). Also add python configuration functions for this to the menu code and switch the MET and jet code to use them. This MR also changes TrigCaloClusterMakerMT into an AthReentrantAlgorithm.
This changes the results of many of the MET chains (as we would hope it would!) so I've updated the references for the affected unit test.
A few problems outstanding
- I've not found an obvious way to validate the clusters produced by this...
EDIT: The failing test was due to the output container not being able to write out, which was in turn due to a combination of ATR-20042 and ATR-19378. For now I've removed it from the EDM lists.
