Remove particles already in G4 10.7.3
XibPlus and XibMinus definition have been added to G4 10.7.3, so it is no longer needed to do so in Gauss and indeed it causes a compilation error.

This ports by hand the change for Sim10
in !1003 and replaces the hotfix in !801 (closed) that was making the LHCb double definition use the same name as in Geant4.
cc: @mimazure, @veltri, @witoldp, @dpopovremove unused copy of src/GiGaPhysUnknowParticle and fix removal in the one in src/particle that is used
This was initially !1016 that has additional commits to introduce in Sim11 the fucntionality to defined particles on the fly.
