Tracking issue for an experimental port of numpy to HPy

[antocuni]

One of our goals is to get numpy to use HPy. We expect this to become the "killer feature" of HPy from the user point of view: a version of numpy which can run fast on alternate implementations, with PyPy being the primary example. This is useful on its own and enables the HPy-ification of the rest of the scientific ecosystem. Moreover, it will help us to drive the design of HPy itself, by using it in a real-word scenario.

Ultimately, when HPy is mature, we hope to convince the numpy maintainers to use it, but for now this would be developed in a fork.

List of subtasks:

• Convert numpy ndarray type to HPy #138
• Port creation and destruction of ndarray objects to HPy #252
• Numpy: port dtype and its static instances to HPy #298

Should this be repurposed to track merging the things in the graal-team/numpy-hpy-port branch back to main? For instance #308 and more.
