Remove unnecessary tool

Closed Petr Balek requested to merge pbalek/athena:hi-remore-unnecessary-tool into 23.0

Removes definition of HIJetClusterSubtractorTool ("cl_subtr_tool") that wasn't used anywhere. Also moves the setup for the correct file name of InputFile for HITowerWeightTool closer to the HITowerWeightTool's definition.
