`iinfo` and `finfo` do not accept `Array`s as input

[mdhaber]

According to the standard, iinfo and finfo are supposed to accept an array (not just a type) for the first argument, but:

import array_api_strict as xp
xp.finfo(xp.asarray([1.]))  # ValueError: data type <class 'numpy.object_'> not inexact
xp.iinfo(xp.asarray([1]))  # ValueError: Invalid integer data type 'O'.
xp.__version__  # 2.2

Crossref numpy/numpy#22977, specifically argument against this type of overloading numpy/numpy#22977 (comment).

Would be easy to tweak array-api-strict to follow the spec; however maybe tighten the spec instead?
