Allow to save detailed hit information in trackless config

Switching on relevant settings to save sihit_ variables for pixel and SCT clusters. These are needed in order to identify which truth particles deposited energy to a cluster (see atlas-flavor-tagging-tools/training-dataset-dumper!526 (closed)) - changes suggested by @tstreble

This will only affect particular samples produced for the development of trackless b-tagging - we will make a specific r-tag once this is merged.
