Skeleton of the new configuration for the Upgrade

Implementation of a new skeleton configuration file for the run-3 DaVinci application exploiting the GaudiConfig2 framework. Note that only a subset of what is needed wil lbe put here. Subsequent PRs will complete the full design, which requires also developments on the Gaudi side.

See issue https://gitlab.cern.ch/lhcb-dpa/project/-/issues/48.

DaVinci job with Upgrade configuration can be run using the following command lines:

• ./run gaudirun.py DaVinci.Configuration:mc (for MC files)
• ./run gaudirun.py DaVinci.Configuration:data (for data files)
