Variorum should check for GPU build before calling GPU APIs (eg utilization or get_thermals etc)

[tpatki]

The for (i = 0; i < P_NUM_PLATFORMS; i++) in the variorum_print_gpu_utilization(void) API should be:

if (VARIORUM_WITH_NVIDIA_GPU || VARIORUM_WITH_AMD_GPU || VARIORUM_WITH_INTEL_GPU)

 for (i = 0; i < P_NUM_PLATFORMS; i++)
    {
#ifdef VARIORUM_WITH_INTEL_GPU
        i = P_INTEL_GPU_IDX;
        break;
#endif
#ifdef VARIORUM_WITH_NVIDIA_GPU
        i = P_NVIDIA_GPU_IDX;
        break;
#endif
#ifdef VARIORUM_WITH_AMD_GPU
        i = P_AMD_GPU_IDX;
        break;
#endif
    }


or something similar

This is a GPU only API and should not be called on other (CPU) platforms. Results in an unimplemented error
