Array API failures with Metal Performance Shaders/torch

[tylerjereddy]

With latest main branch on an ARM mac SCIPY_DEVICE=mps python dev.py -n test -j 16 -b all results in 189 failures.

Some of the failures will be hard/impossible to avoid because torch doesn't support all ops on that device just yet. However, many of the failures do look avoidable given TypeError: Cannot convert a MPS Tensor to float64 dtype as the MPS framework doesn't support float64. Please use float32 instead. is probably something that could be shimmed around in some places perhaps.

On the other hand, https://data-apis.org/array-api/latest/API_specification/data_types.html is pretty clear on requiring support for those types, so we'd likely only want to shim around cases where a violation of the standard doesn't occur I suppose.

Test skips could be added with clear explanations if we thought this backend merited it.

[rgommers]

I think that guidance in the array API standard may be loosened a bit. However, in SciPy we do require float64 support in order to run tests for the backend. It's just too fundamental for us. float32-only code may work, but supporting that in the test suite would be a lot of churn. We should probably punt on that for now, and document in http://scipy.github.io/devdocs/dev/api-dev/array_api.html that float64 is needed for the test suite to work.
