FTAG OnnxUtil and OnnxOutput class renaming to SaltModel and SaltModelOutput
Rename of the OnnxUtil class to be SaltModel to avoid confusion with the AthOnnxUtils/OnnxUtils class
as discussed here
I also moved OnnxOutput as SaltModelOutput and renamed the variables called m_onnxUtil as m_saltModel
NB: the current MR is for main because some files are using the OnnxUtil class in the main branch while those files are not existing in 24.0
e.g. https://gitlab.cern.ch/atlas/athena/-/blob/main/PhysicsAnalysis/AnalysisCommon/LeptonTaggers/src/DecoratePLIT.cxx
A corresponding MR has been thus provided for the 24.0 branch: !77847 (merged)
