The NVIDIA CUDA Python bindings are required to link C/C++ code with Numba kernels, because it compiles them with NVRTC. This means that full float16 support also needs those bindings. If we supported NVRTC with the ctypes bindings, then float16 support would always be available.

Previously this was not implemented because it might have been tricky to locate NVRTC, as it wasn't present in cudatoolkit conda packages. However, from CUDA 12 onwards, the cudatoolkit (or cuda-toolkit?) packages on conda-forge will have it available, so locating it should be less of an issue.
