Store a VDB grid in a new VDB primitive and add the primitive to a geometry detail.

Parameters
gdpthe detail to which to add the new primitive
grida grid to be associated with the new primitive
srcif non-null, copy attributes and groups from this primitive
nameif non-null, set the new primitive's name attribute to this string; otherwise, if src is non-null, use its name
