Support multiple CUDA compute capabilities

### Describe the bug

When specifying multiple CUDA compute capabilities (e.g. `-fsycl-targets=nvidia_gpu_sm_62,nvidia_gpu_sm_61`), the runtime will only ever choose the first one and ignore others.

I believe the relevant code is [here](https://github.com/intel/llvm/blob/ca955e538171cb7b7eb07734dd5c2b958c84901c/sycl/source/detail/helpers.cpp#L52), always picking the first `llvm_nvptx64` it finds.

The correct behavior would be to choose the latest compute capability included not greater than the one of the device.
So if I compile for sm_60, sm_61, sm_62 in any order and I have a Pascal (sm_61) GPU; it should only try the sm_61 program.

### To reproduce

```cpp
#include

int main() {
sycl::queue queue{sycl::default_selector_v};
queue.submit([&] (sycl::handler& cgh) {
auto os = sycl::stream{128, 128, cgh};
cgh.single_task([=]() {
#ifdef __SYCL_CUDA_ARCH__
os << "CUDA_ARCH " << __SYCL_CUDA_ARCH__ << "\n";
#else
os << "Not CUDA\n";
#endif
});
});

return 0;
}
```

With a Pascal (sm_61) GPU:
- `icpx -fsycl -fsycl-targets=nvidia_gpu_sm_60,nvidia_gpu_sm_61,nvidia_gpu_sm_62 main.cpp` prints `CUDA_ARCH 600` instead of the correct `CUDA_ARCH 610`.
- `icpx -fsycl -fsycl-targets=nvidia_gpu_sm_62,nvidia_gpu_sm_61,nvidia_gpu_sm_60 main.cpp` errors out instead of printing `CUDA_ARCH 610`.
