for #30574 0130cff

• the backport is correct; the only difference in the PR diffs compared to the master version is in SeedGeneratorFromL1TTracksEDProducer.cc due to the change of name of TrajectorySeed::RecHitContainer typedef (introduced recently in the 11_2_X). This code is to be used for HLT developments; it is currently not a part of the standard workflows.
• jenkins tests pass and comparisons show no relevant differences

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_11_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_2_X is complete. This pull request will now be reviewed by the release team before it's merged. @silviodonato, @dpiparo (and backports should be raised in the release meeting by the corresponding L2)
