hgridshift/vgridshift: defer grid opening when grid has already been opened
Relates to #2115
With the fix of https://github.com/OSGeo/PROJ/pull/2128, transforming between
EPSG:4326+3855 and EPSG:4269+5703 leads to many operations with many grids,
and opening a file handle for each operation saturates the limit of 1024
file handles opened simunalteously. This fix defers grid opening when a
transformation has already been instanciated with the same grid.
