Subject: [PATCH] GeoPcon and GeoPgon: extended the interface to allow const
access to memory buffers of the member vectors
This change was implemented to simplify Geo2G4 translation. In particula, it should allow
passing the buffers held by GeoPcon and GeoPgon to the constructors of G4Polycone and
G4Polyhedra respectively (see the discussion on https://gitlab.cern.ch/atlas/athena/-/merge_requests/74223)
