Draft: feat: implement `__cuda_array_interface__`

https://numba.readthedocs.io/en/stable/cuda/cuda_array_interface.html

This is supported by:

• pycuda
• numba
• cupy
• torch
• nvcv https://github.com/CvCuda/CV-CUDA
• maybe by tensorflow in future: https://github.com/tensorflow/tensorflow/issues/29039

Also allow to execute with cupy (https://docs.cupy.dev/en/stable/index.html) instead of pycuda

TODO:

• check that pointers in correct CUDA context and if not import into current
• make execution with pycuda aware of __cuda_array_interface__
• what/how to test
