Fixed LAr/Tile/Muon GeoModel code accessing materials defined either in SCT or in TRT
We have several cases in GeoModel
when some subsystem is accessing materials
defined by other subsystem. This can lead to crashes when we build a geometry
layout where the latter subsystem's material definitions are missing (e.g.
InDet materials in SLHC layouts).
This commit fixes some of such cases by copying several SCT and TRT material definitions over to STD materials, and pointing the client code to the new location of these materials.
