Enable c++20 in top level cmake. Keep c++17 for GrpcInterface, as the protoc tool does not work with c++20.
Several code adjustments to fix compiler issues.
* Moved UnitSystem from RiaEclipseUnitTools to RiaDefines.
- Renamed UnitSystem to EclipseUnitSystem
- Replaced header includes and removed obsolete includes of RiaEclipseUnitTools.h
* Moved result name functions into separate file.
* Minor cleanup
