• Exact backport of Added links from LowPtGsf to PackedCandidates and LostTracks in MiniAOD #26031, now merged in the master
• The new maps only add up to the miniAOD output when the bParking era is set: jenkins tests pass and show no differences
• As in the master, there is a check to be done on the lowPtElectron code which jumps from time to time on some all 0 parameters tracks: this is independent from this PR, however, which can be therefore integrated while that issue is getting dedugged

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_2_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_10_6_X is complete. This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
