Use Python implementation for AdvancedInSubtensor1

MapIter was removed from the public numpy C-API in
version 2.0, so we raise a not implemented error to
default to the python code for the AdvancedInSubtensor1.

The python version, defined in `AdvancedInSubtensor1.perform`
calls `np.add.at`, which uses `MapIter` behind the scenes.
There is active development on Numpy to improve the efficiency
of `np.add.at`.

To skip the C implementation and use the Python implementation,
we raise a NotImplementedError for this op's c code if numpy>=2.0.
