ContourMapProjection: Replace references with naked pointers

Replace reference members and constructor parameters with raw pointers in
RigContourMapProjection and subclasses. Remove cvf::ref usage in
RigEclipseContourMapProjection. Add updateRealizationData() to allow
swapping active cell info and result data per realization without
rebuilding the grid mapping.
