[francescobrivio]

PR description:

This PR adds the realistic vertex smearing scenario for 2021 PilotBeams data.

• The BeamSpot parameters are extracted from run 346512 (Fill 7531) using the ExpressPhysics FEVT dataset, the legacy BS workflow, and refitting trks and PVs with the latest and greatest TkAlignment conditions.
• The BPIX barycenter comes from this twiki

PR validation:

Code compiles

Backport:

Not a backport, a backport to 12_2_X is available in #36440
