HGTD_GeoModel improvements and cleanup

• Moving to ATH_MSG_XYZ macros for messages as requested in !39931 (merged)
• Removing confusing printout of unused db parameters (z positions of cylindrical volumes) as pointed out by @menke in ATLSWUPGR-119
• Removing hardcoded overrides of db values that were anyway identical to what's in the db (peripheral electronics)
• No longer creating volumes of air for tolerances
• Changed material of cooling pipes from stainless steel to titanium

Some of these changes go towards ATLSWUPGR-91.

Tagging @lshan and @dshope for info. Will upload some checks here before moving this forward, but feel free to have a look at the changes in the meantime. Update: checks were performed and things look good, details in the comments.
