Implementation of advanced features in Upgrade Configurable

Implementing advanced features in DaVinci Configurable for Upgrade. List of the new features:

• enabling the possibility to pass arguments from the command line
• adding a new DaVinci property for passing the python file containing the user algorithms
• adding the configuration of unpacking and MC association for simulated samples; (for the moment it is implemented similarly to the old configuration, it will be updated in a future MR. See https://gitlab.cern.ch/lhcb-dpa/project/-/issues/63)
• adding functions for propagating the FSRs
• getting rid of the GaudiSequences
• implement the Moore selection framework
• adding a few extra useful functions
