[FEA]: Support `load_nvidia_dynamic_lib()` `"cuda"`, `"nvml"`

These libs are installed as part of the CUDA driver and can be reliably found via the dynamic loader system search.

• "cuda"
  • Linux: libcuda.so.1
  • Windows: nvcuda.dll
• "nvml"
  • Linux: libnvidia-ml.so.1
  • Windows: nvml.dll

The "cuda" lib can come from cuda-compat (Linux only) but it must be on the system path, so we can simply rely on the dynamic loader and do not need to search in multiple places.
