better automatic handling of default 2026 geometry

[mmusich]

PR description:

This is a follow-up to #45764, in order to enforce that the the "default" 2026 geometry is taken from one unique place (in this case: Configuration/Geometry/python/defaultPhase2ConditionsEra_cff.py).

PR validation:

Checked out the following packages

git cms-addpkg Geometry/TrackerGeometryBuilder/ SimTracker/TrackerMaterialAnalysis RecoTracker/MkFit SLHCUpgradeSimulations/Geometry Alignment/OfflineValidation

in which the default geometry is used and check that all the unit tests run fine with: scram b runtests

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

[cmsbuild]

Milestone for this pull request has been moved to CMSSW_14_2_X. Please open a backport if it should also go in to CMSSW_14_1_X.

[mmusich]

@srimanob now that this PR is moved to CMSSW_14_2_X milestone, shall I backport it to CMSSW_14_1_X too or is it an overkill? (I suppose we won't change defaults in CMSSW_14_1_X anymore now).

[srimanob]

Hi Marco,
To me, it is fine to keep 14_1 as is. I don't think we will touch it for Phase-2.
