Introduce Phase 2 FastSim (tracker) workflows

[kpedro88]

PR description:

The culmination of substantial work primarily by the IISER Pune and Johns Hopkins University groups, with assistance from SIM and the tracker DPG.

Major developments:

• New definition of FastSim simplified tracker geometry and material introduced to correspond to Phase 2 upgrade
• New pixel resolution histograms from JHU at phase 2 pixel histograms (from JHU) cms-data/FastSimulation-TrackingRecHitProducer#5
• Phase 2 digitization sequences updated to work with FastSim
• Updated FastSim tracking iterations to correspond to Phase 2 sequences
• Workflows added for D110 (development baseline for past ~year) and D121 (current default)

Technical developments:

• Change handling of FastSim geometry sequences to adapt more easily to multiple Phase 2 geometries
• Add an Era "Util" to make temporary FastSim-specific workflow changes to Phase 2 Eras
• Simplify some old code in DIGI aliases

Still to come later:

• Realistic outer tracker resolutions
• Overall physics validation
• Move beyond tracking-only reconstruction in workflows

PR validation:

Ran new workflows 36434.0 and 36834.0 successfully.

Also ran Run 3 workflow 16434.0 to ensure previous sequences were not disrupted by these changes.

@kpedro88 is it worth having one FastSIM (such as 36434.0) in the limited matrix?

[kpedro88]

I was thinking about it, but I think we are not quite ready yet. Let's start with IB tests only and see how it goes.

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. @sextonkennedy, @mandrenguyen, @ftenchini (and backports should be raised in the release meeting by the corresponding L2)
