Add `VirtualArray` in the input/output signature of the nplikes' functions when required

I m pretty sure _all_ of our nplike functions will now need `| VirtualArray` in the input signature. Can you update the nplikes, and the array modules, etc? Originally posted by @agoose77 in ...

Investigate the usage of `cached_property` for `materialize` and `is_materialized` in `VirtualArray`

Perhaps this is a good candidate for https://docs.python.org/3/library/functools.html#functools.cached_property Originally posted by @agoose77 in https://github.com/scikit-hep/awkward/pull/3364#discussion_r2002974502 ...

`array_equal`/`array_almost_equal` does not take into an account nested layouts

Hi awkward. Thanks for this great codebase, and I m sorry if I m asking a question which has been answered elsewhere. I looked around and couldn t find anything. Do you understand why array_equal gives ...

Should the generator of a VirtualArray always yield unique copies of an array?

Do we assume that the result of each generator invocation is unique (i.e. doesn t need to be copied)? That would be nice, and means that this is correct. Originally posted by @agoose77 in https://github.com/scikit-hep/awkward/pull/3364#discussion_r1985119884 ...

Should VirtualArrays allow JAX as nplike?

Why this restriction? We do allow NumPy → JAX, so we should allow Virtual[Numpy → JAX, no? Originally posted by @agoose77 in https://github.com/scikit-hep/awkward/pull/3364#discussion_r1985084963 ...

update `_backends` so that we don't have to hard-code the nplike-to-backend relationship

This is much better. In future, I d like to update `_backends` so that we don t have to hard-code the nplike-to-backend relationship. Originally posted by @agoose77 in https://github.com/scikit-hep/awkward/pull/3364#discussion_r1985081845 ...

Revisit `.raw()/._raw()` for `VirtualArray`s

In https://github.com/scikit-hep/awkward/pull/3364, we make .raw()/._raw() calls materialize. Some more thinking can be put into whether this should be the case. Perhaps we need a materializing and a non ...

`ctypes` abstraction is not scoped to NumPy only

It seems like we some-where rely on array.ctypes internally. We should try and abstract that to inside the nplike / kernels.

Revisit `VirtualArray` handling in `is_own_array` in `array_module.py`

I don t think this is a good idea if we can avoid it — a VirtualArray _is _not_ the same as e.g. a Jax array or CuPy array. We also use this to memoize `type(array)→nplike` which would fail for ...
