ENH: add __array_api_version__

* this is in part a copy of the NumPy patch applied at:
numpy/numpy#22365
and is related to this failure we were seeing with
`hypothesis`: kokkos#65 (comment)

* the standard section related to this is:
https://data-apis.org/array-api/latest/future_API_evolution.html#versioning

* unpin `hypothesis` in our CI as a result; to be fair,
this is the solution @ShahzadUmair wanted from the start
I think

* the updated testing behavior required me to cherry-pick
some data type info improvements from kokkosgh-97
