Subject: [PATCH] GH-12594: [Python][GPU] Remove inherently crashy CUDA test

Remove a CUDA test that tries to access an invalid pointer (after the owning resource was deallocated).

On old CUDA setups it used to raise an exception:
```
Cuda error 1 in function 'cuMemcpyDtoH': [CUDA_ERROR_INVALID_VALUE] invalid argument
```
but more recently it has simply started crashing.
