Description
Part of #12514
In the long term, we want np.argmin to become that gufunc - but in the short term, we can just wrap it to deal with any interface quirks.
In particular, argmin allows multiple axes to be specified.
Blocked by #12518, needed to give access to ->f->compare in the inner loop

Research direction
Start by reading the parent issue #12514 and the blocking issue #12518, then inspect the existing np.argmin and np.argmax implementations and gufunc conventions. The work is done when gufunc forms exist, handle the noted interface differences such as multiple axes, and the dependency provides access to ->f->compare.
