[15.0] Fix missing CaloParticles from pileup

[AuroraPerego]

PR description:

Since CMSSW_15_0_0_pre2, there are no CaloParticles from pileup due to a wrong ioread rule that led to misreading the pileup files. This PR fixes the ioread rule for ClassVersion 12 and below (the crossedBoundary_ variable was introduced with ClassVersion 12, requiring two different rules).

In addition, a processModifier to consider also CaloParticles from pileup in the associators (leading to the creation of tracksters from pileup) has been added.

PR validation:

to be tested with 29888.208 and 301.0
