PR description:

This is a backport of #35380 to CMSSW_12_0_1.

This PR addresses a few minor corrections on the PPS geometry in the Pixel sensors and complies the material names in the reco geometry as stated in #34927. The position of the Silicon wafers has been move down to 250um w.r.t. the bottom foil and the envelopes with sensors ad flexible cables has been enlarged to avoid volume overlaps. Besides, the U shape of the Aluminum supports has been changed to a plain squared piece. A detailed list of the file changes and visualization of the new changes in the Pixel sensors is given in this twiki.

Includes updated on both DDD and dd4hep files and keeps the default dict2021Geometry.py for 12_0.

PR validation:

The new changes in the geometry have been validated with the full CMS geometry dump for visualization and overlap check with tolerance 0.01, plus direct and full simulation to confirm hits in both pixel and timing detectors. The position of the pixel sensors have been checked with direct simulation here.

if this PR is a backport please specify the original PR and why you need to backport that PR:

PR #35380, needed to update PPS geometry for Run3.

All changes follow the Naming Rules for new XML files in geometry.
All workflow tests done.

It involves the following packages:

  • Geometry/CMSCommonData (geometry, upgrade)
  • Geometry/VeryForwardData (geometry)
  • Geometry/VeryForwardGeometry (geometry)

@civanch, @Dr15Jones, @makortel, @cvuosalo, @ianna, @mdhildreth, @cmsbuild, @AdrianoDee, @srimanob can you please review it and eventually sign? Thanks.
@bsunanda, @fabferro, @jan-kaspar, @fabiocos, @slomeo this is something you requested to watch as well.
@perrotta, @dpiparo, @qliphy you are the release manager for this.

I'll correct the rebase to avoid the unittest error.

@bsunanda I moved to #35391 to fix the issue with unittest. If needed later I'll remove those files from the PR.
