Actually applies the AstrometryMapping and evaluates the derivatives w.r.t the fitted parameters.
This is grouped into a single call because for most models, evaluating the derivatives w.r.T parameters is not much longer than just transforming
Implemented in lsst::jointcal::SimplePolyMapping, lsst::jointcal::SimpleAstrometryMapping, and lsst::jointcal::ChipVisitAstrometryMapping.
