[GeoMechanicsApplication] Convert piping interface element, to 1D line element

Follows from [GeoMechanicsApplication] Prepare piping showcase for Delft Software Day which was deleted.

Added first implementation

This was quick and dirty for showcase but a good starting point for a more robust implementation

Current hurdle is that the results between old DGFlow, current DGeoFlow (Kratos InterfacePipeElement) and this do not match.

The piping algorithm seems to function as required, however the fine tuning of the model to fit the results "expected" is somewhat difficult. In discussions with Vera \ Lisa about how to proceed.
