InDetToolsConfig.py: Set TrackStateOnSurfaceDecoratorCfg.AddExtraEventInfo only for cosmic reco

The Tier0 logs show per-event warnings like

WARNING unable to find proxy for  ( 'ComTime' , 'StoreGateSvc+TRT_Phase' )

I traced this back to the public tool TrackStateOnSurfaceDecorator/DFTrackStateOnSurfaceDecorator used by the algorithm DFInDetTSOSKernel. Reading through the related code, I conclude that decorating the xAOD::EventInfo object with a TRT event phase is only intended for cosmic reconstruction. This MR switches the ExtraEventInfo property to false for all other cases and thus suppresses the per-event warning.
