Unify jet hit association pipelines

This MR is a follow up to Dan's MR !959 (merged) which laid the ground work for a unified pipeline in jet hit association between hit writing and inference. Relates to issue #178.

Description

Currently in the TDD, there is the HitWriter routine for performing the jet hit association and a selection on clean hits and writing the hits to an h5 file. In case of inference, there is a JetHitAssociationAlg used which does not yield the same results for association as the written one --> replace the HitWriter, add ca blocks which perform the same tasks

Plan for the JetHitAssociation block:

• add CleanHitDecoratorAlg which replaces the cleanHits function of the HitWriter, apply to both Pixel and SCT container
• add the right variables to both container using HitDecoratorAlg
• apply the JetHitAssociationAlg from Athena as it is right now (using all hits) to both containers
• new Alg that concatenates the two element links from SCT and Pixel and performs the selection (reject bad hits, keep only maxHits hits)
• calculate jab variables in custom consumer

--> after the block, write out hits based on the combined element link

Review checklist:

• CI Passing
• Comments addressed
• Source branch is up to date with target
