Is your feature request related to a problem? Please describe.

Quoting from a chat:

Someone, somewhere, will want to know the "real" cudart version and not what was used to build cuda-python.

Currently runtime.getLocalRuntimeVersion() is implemented using a direct dlopen() call:

• cuda-python/cuda_bindings/cuda/bindings/cyruntime.pyx.in

  Line 1887 in 1cb8a6f

  handle = dlfcn.dlopen('libcudart.so.12', dlfcn.RTLD_NOW)

Describe the solution you'd like

The direct dlopen() call should be replaced with a call to path_finder, similar to existing calls, e.g. here:

• cuda-python/cuda_bindings/cuda/bindings/_bindings/cynvrtc.pyx.in

  Lines 52 to 55 in 314060c

  	handle = path_finder._load_nvidia_dynamic_library("nvrtc").handle
  	{{else}}
  	with gil:
  	handle = <void*><uintptr_t>path_finder._load_nvidia_dynamic_library("nvrtc").handle
