Fix "Max number of processor cores" in the GUI

• In the Khiops GUI, the "Max number of processor cores" is now bounded by the number of physical cores (not minus one). 2 now useless methods are removed from KWSystemParametersView:
  • ComputeCoreNumber
  • ComputeRequestedCoreNumber
• 2 methods used RMResourceConstraints::GetMaxCoreNumberOnCluster() wrongly. It returns the number of cores on the system without regard to the user constraints and resource requirements.
