Add virtual methods (isFileBased, filePath, setFilePath) to RimSurface base
class. Implement these in RimFileSurface and RimRegularFileSurface to provide
a common interface for all file-based surfaces.
Replace class-specific methods (setSurfaceFilePath/surfaceFilePath) with the
common interface methods (setFilePath/filePath) in both RimFileSurface and
RimRegularFileSurface. Update RimEnsembleSurface to use the common interface.
This enables polymorphic treatment of file-based surfaces without changing
the inheritance hierarchy or breaking backward compatibility.
Fixes#13296
* Refactor interface to PdmObjectHandle and PdmFieldHandle
Return objects instead of passing in structures as parameters
* Add nodiscard to several functions
* Remove redundant this->
* Rename to ptrReferencedObjectsByType
* Update titles after dropping vectors into plot
* Do not replace _Name variables
* Make sure signals are wired when opening a project file
* Add auto name field and set default on
* Remove includes from header files
* Performance : Improve surface import
* Performance: Use opm when importing files
* Surface : Use the triangle size as basis for the maximum search distance
* Performance : Resample surfaces in parallell
* Performance: Import file surfaces in parallell
* Ensemble Surface : Create one ensemble per surface
