Initialize device_id in cuda_call & rocm_call (#20933)

### Description
<!-- Describe your changes. -->

Initialize `device_id` with `-1` in  `cuda_call` and `rocm_call`.

### Motivation and Context

From PyTorch code:
https://github.com/pytorch/pytorch/blob/bb2de3b10120f91afce8da6233094076713f673d/c10/cuda/CUDAFunctions.cpp#L217-L324

If `cudaGetDevice` or `hipGetDevice` failed, an uninitialized `int`
would produce a random number that changes during each run:

```text
[with ERRTYPE = hipError_t; bool THRW = true; std::conditional_t<THRW, void, common::Status> = void] HIP failure 101: invalid device ordinal ; GPU=32741 ; hostname=e6724be2a31a ; file=/onnxruntime_src/onnxruntime/core/providers/rocm/rocm_common.h ; line=66 ; expr=hipGetDeviceProperties(&deviceProp, 0); 
```

Notice the `GPU` value above. Using `-1` would clearly indicate such
failure and avoid confusion.
