Configure Geant4 physics list to be similar to GeantV

[civanch]

For comparison of the default Geant4 and new GeantV tracking an equivalent to GeanV EM physics constructor is proposed, where only gamma, e+, e- interactions are included.

This PR should not affect any production.

A new Pull Request was created by @civanch (Vladimir Ivantchenko) for master.

It involves the following packages:

SimG4Core/PhysicsLists

@cmsbuild, @civanch, @mdhildreth can you please review it and eventually sign? Thanks.
@makortel this is something you requested to watch as well.
@davidlange6, @slava77, @fabiocos you are the release manager for this.

@bsunanda , this is EM physics fully equivalent to the 2018 GeantV physics (I have checked with GeantV developers). The PhysicsList name is "DummyPhysics". We can rename this if needed. This Physics List may be used for head-to head Geant4/GeantV comparison. In GeantV decay is not planned for this year but the DecayPhysics is left here , because allows instantiate all particles.

If the full EM physics is needed to be compared then FTFP_BERT_EMM or EML can be directly used for primary gamma, e+,e-, neutrino.

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. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)

[civanch]

@kpedro88 , this is one to one GeantV PhysList.

[kpedro88]

thanks @civanch
