Backport 10a8d5c from #1998

…nadgrids= and +pm= (OSGeo#1998)

Fixes issue reported at
https://lists.osgeo.org/pipermail/gdal-dev/2020-February/051749.html

The generated pipeline assumes that the input coordinates for the grid transformation
were related to the non-Greenwich based datum, so we must compensate for that and
add logic to go back to Greenwich.
