GH-12594: [Python][GPU] Remove inherently crashy CUDA test (#51206)
### What changes are included in this PR?
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.
### Are these changes tested?
By existing CI tests. This should fix a crash in the CUDA Python CI.
### Are there any user-facing changes?
No.
