Fix T86875: "Show on Cage" crash for geometry nodes primitives

Without `calc_object_remap` turned off in the conversion to and from
BMesh for the primitive nodes, the `CD_ORIGINDEX` custom data layer
has incorrect values. By using a different function to do the conversions,
we can avoid this problem.

Thanks to Jacques for finding the fix here.
