Fix UT geometry and tracking

Works with following MRs

• !368 (merged)
• Boole!501 (merged)
• lhcb-datapkg/PRConfig!335 (merged)
• lhcb-conddb/DDDB!79 (merged) and lhcb-conddb/SIMCOND!143 (merged) , to be able to produce samples (Gauss+Boole) consistent with this

This MR is to correct UT geometry flaws, including

• fix wrong stave staggering and positioning (swap X corrections between two sides, reverse staggering)
• fix overlaps
  • adding UTEpsilon (1μm) between volumes to avoid surface sharing
  • removing Air from UT volumes to avoid overlaps (except lvSectorHole)
  • splitting lvUTPipeHeater into two "InUT" and "InMagnet" segments
• fix tracking issues
  • fix DeUT::getLayerGeom
  • fix assignment of stereo angle issue
  • fix localU and localUToStrip
• other improvements
  • fix End-of-stave structure
  • fix UTBox dimension
  • validated correspondence of stave new nickname (with new ChannelID, C/A sides) and old name (old ChannelID, a/b stations)
  • improving visualization
