This pull request is fully signed and it will be integrated in one of the next CMSSW_14_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_14_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @rappoccio, @sextonkennedy, @antoniovilela (and backports should be raised in the release meeting by the corresponding L2) |

PR description:
Backports bug fixes to a couple of spin locks to 14_0_X. This backports PRs #44447 and #44517. See Issue #44413 for related discussion.
These bugs were causing rare seg faults in IB tests. We believe they mostly only occurred when concurrent lumis were configured and multiple lumis were actually being executed. The failure actually observed seemed more common when lumis containing no events were being processed because it requires global end lumi transitions running at the same time. Even in those circumstances the failures are rare.
PR validation:
Relies on existing tests.
