Align ITk TrackStateOnSurface configs on Run 3

Thomas Streblerrequested to merge
tstreble/athena:ITkTSOS_Cfg into main

Reproduce Run 3 configs with ITk. In particular, changes msosLink to Reco_msosLink by setting DecorationPrefix = "Reco_".

Also minor clean up to TrackStateOnSurfaceDecoratorCfg removing kwargs.setdefault("DecorationPrefix", "") since it is set above to kwargs.setdefault("DecorationPrefix", "notSet")
