Updating the LengthIntegrator tool to dump an ntuple instead of TProfiles with information of volumes/material/X0/L0

Updating the LengthIntegrator to dump a small scaled ntuple with a tree, rather than plots directly. The original approach was quite cpu heavy and the jobs were slow. A simple rootmacro has been made that runs over the output that re-produce already similar results as previous, but need to figure out a place for this to live.

Still need to decide whether we want to keep the old approach as an alternative or if all related code can be safely removed.
✔ Removing plots

Using if(m_geoModelSvc->geoConfig()==GeoModel::GEO_RUN4) { m_isITk = true; } to decide which detector it is, might exist a better way to get this information in Sim?
✔ Updated so this is configured via the postinclude of the LengthIntegrator

For the record, the plotting macro is uploaded to here: https://gitlab.cern.ch/Atlas-Inner-Tracking/materialplotting This could be moved into a more proper location so it can be used for ART, but I'm not sure where that would be
