ENH: test binops with float_array, int_scalar combinations

[ev-br]

Previously, we only tested the matching type/dtype combinations, i.e.

• float_array, float_scalar
• int_array, int_scalar
• bool_array, bool_scalar

So float_array, int_scalar combinations were missing (cross-ref #364)

Tested locally with 10_000 examples on array_api_strict, numpy, cupy, torch and jax, and 1000 examples on dask. No new failures.

TODO

• clip float array, int min/max
• searchsorted -- in WIP: searchsorted: allow x2 to be python scalar #394

[ev-br]

Updated test_clip. Caught a failure on JAX with

E           ========== FAILING CODE SNIPPET:
E           xp.clip(Array(0, dtype=uint64), **kw) with kw = {'min': 0, 'max': 9223372036854775808}
