[15.0.X] add missing defaults to MkFitProducer::fillDescriptions

[mmusich]

backport of #47575

PR description:

While trying to parse in confDB the resulting menu from the customization proposed at CMSHLT-3421, it was noticed that certain parameters in MkFitProducer were not assigned the right cms type.
This was analyzed as a lack of appropriate defaults in the fillDescriptions of the producer, which as per coding rule 6.14 link is needed for modules used at HLT.

PR validation:
