JetRecTools: add the decoration of the orignal object

In the tau reconstruction, we store cluster links to the clusters used in the seed jet for later analysis (both in Athena, and AnalysisBase). For Topo jets, these cluster links point to a shallow copy container of CaloCalTopoContainer, i.e. LCTopoOriginContainer. Since jets may not be stored in AOD in R22, the links will be invalid. We would prefer to store cluster links to the original CaloCalTopoContainer instead of the shallow copy container. To make it easy, an decoration of the original object is added to the shallow copy version for later access.
