NVIDIA JIT LTO Library (CUDA 12)

The `nvidia-nvjitlink-cu12` package is a metapackage that facilitates the installation of the NVIDIA JIT LTO (Just-In-Time Link Time Optimization) library, `nvJitLink`, as part of the CUDA Toolkit for CUDA 12.x environments. It ensures the presence of the native C-based `nvJitLink` library, which is used by other Python libraries like CuPy and Numba-CUDA for advanced GPU code compilation and linking at runtime. This package itself does not expose direct Python APIs for JIT linking. The current version is 12.9.86, and it follows the CUDA Toolkit's release cadence.
