Geometry D110: failure in creating Tracker misalignment scenarios

[mmusich]

This issue stems from PR #45764.
After #45370 a bunch of unit tests relying on deprecated geometries have started to fail, which was fixed at #45764.
The default geometry (D110 - i.e. Tracker T35) cannot be used for createRandomlyMisalignedGeometry_Phase2_cfg.py as doing so as in:

This will be solved by #45993

[mmusich]

solutions proposed:

• bugfix: remove DoubleSensGeomDet (ph-2 InnerTracker) #45993 (master, CMSSW_14_2_X)
• backport in 14_1_X of PR#45993: bug-fix: remove DoubleSensGeomDet (ph-2 InnerTracker) #45996 (CMSSW_14_1_X)

[mmusich]

@cms-sw/alca-l2 @cms-sw/geometry-l2 in order to be sure to process correctly ph2 samples produced in CMSSW_14_0_X, how open would you be to a backport of #45993 to that cycle?

@cms-sw/alca-l2 @cms-sw/geometry-l2 in order to be sure to process correctly ph2 samples produced in CMSSW_14_0_X, how open would you be to a backport of #45993 to that cycle?

In the PR description of #45993 is written "removing the DoubleSensGeomDet introduced for phase-2 Inner Tracker modules (T33 tracker geometry and following T35, T36, T37, T38 and T39) but actually not used in the code (and unlikely to be used in future)." Given that such PR removes some deprecated geometries, and it can help processing correctly Phase2 samples, for AlCaDB I don't see counterindications to the backport.
