"Modernize" CMake configuration

This MR align the content of the LHCb Geant4 project with that of the official Geant4 repository, with the addition of LHCb patches, physics lists and tests.

The Geant4 version used as baseline is tag lhcb/v106r2p5 from https://gitlab.cern.ch/lhcb/Geant4-srcs

Note This MR replaces !78 (closed) (see !78 (comment 5039250))

do not squash the commits in this MR as they are meant to pull original Geant4 history into this repository.

changed title from Draft: Revert "Delete LICENSE" to "Modernize" CMake configuration

@gcorti, WRT !78 (closed) I decided to use the 4th digit CMake allows in a version to track the changes in the LHCb patches, so v106r2p4 → 10.6.2.4.

We will have to decide if we want to tag with the v106r2p4 convention or use something closer to the official Geant4 tags, like v10.6.2.4. I do not know the impact this change would have in the current deployment model, so I'd stick to the current convention for a while.

@mimazure, you can try to build Gaussino on top of this MR for Geant4.
