Integration of sexaquark simulation code (for EXO-24-003)

[lowette]

CMSSW integration of sexaquark simulation code.

This PR adds code for sexaquark simulation starting from HepMC input files. It adds the new sexaquark particles, the inelastic interaction, the neutron annihilation, and a looping mechanism to increase the chance of an interaction, plus other necessary classes and files. CustomPhysicsList is extended to this new interaction for the anti-sexaquark.

Nothing in ordinary CMS running should be affected, GEANT will only use this code when a particle with pdgId -1020000020 is found (which is the proper code for a sexaquark of content uuddss).

This code integration happens following the presentation in the EXO MC&I meeting here:
https://indico.cern.ch/event/1379001/#3-sexaquark-simulation-in-cmss
We were requested to integrate the sexaquark simulation code, and to validate our private productions with a central simulation. For the latter, we will want to do a backport to CMSSW_10_2_X once merged in the master.

The code was tested in the latest 14_1_X integration build using the new python config added in the CustomPhysics/test directory.
This was not expected to affect any runTheMatrix tests. I ran the tests for completeness (runTheMatrix.py -l limited -i all --ibeos) which flagged no problems.

@smuzaffar , sorry, I cannot interpret tests as "approved". This does not related to this PR but bot report is not clear to me.

please test

lets re-run to get clean tests: see #45116

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