fixing typo in NSWCalibTool and MmRdoToPrepDataTool
This MR fixes typos introduced in !31326 (merged) which created MMPRDs with a local positon of dx and a wrong time since the default t0 had the wrong sign. Also fixing the units of reciprocalSpeedOfLight and actually making it the reciprocal.
Adding urgent since this breaks MM reco. This fix is alsoTargeting:21.9 and ~"alsoTargeting:master" but labels are not put since the sweep should maybe happen with the sweep of the original MR
