Fix loc/iloc.__setitem__[:, loc] with non cupy types

[mroeschke]

Description

Discovered in #16652, DataFrame.iloc/loc.__setitem__ with a non-cupy type e.g. "category" failed because the indexing path unconditionally tries to cupy.asarray the value to be set which only accepts types recognized by cupy.

We can skip this asarray if we have a numpy/pandas/cudf object
