[felicepantaleo]

PR description:

This is a backport of #33318 to 11_3_X
This PR introduces SimTracksters.
SimTracksters are Tracksters objects containing layerclusters that are associated to the same SimClusters.
They are run in the HGCal Validation Sequence and kept only in FEVT.
They will be useful for benchmarking the pattern recognition as they will produce the best possible tracksters directly from simulation.

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_11_3_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
