Refactor: migrate fourteen more collections to caf::PdmObjectCollection<T>

Migrated to the templated base, preserving each collection's existing XML
field keyword for project-file backward compatibility:

- RimEnsembleFractureStatisticsCollection
- RimEclipseInputPropertyCollection
- RimPlotDataFilterCollection
- RimGeoMechContourMapViewCollection
- RimIntersectionResultsDefinitionCollection
- RimCustomObjectiveFunctionCollection
- RimStimPlanModelTemplateCollection
- RimEnsembleWellLogsCollection
- RimEclipseContourMapViewCollection
- RimSeismicViewCollection
- RimGridInfoCollection
- RimEclipseStatisticsCaseCollection
- RimWellIASettingsCollection
- RimVfpDataCollection

External callers that accessed the old public/named array fields directly
(RimEclipseInputPropertyCollection::inputProperties,
RimEclipseStatisticsCaseCollection::cases) now use addItem/items() from
the base. RimCustomObjectiveFunction.h replaced its include of the
collection header with a forward declaration to break the new include
cycle introduced by the migration.
