CUDA nvcc Compiler (CUDA 12)

The `nvidia-cuda-nvcc-cu12` package provides the NVIDIA CUDA C/C++ compiler (`nvcc`) as a Python wheel for CUDA Toolkit version 12. It enables Python-based build systems and projects (e.g., those using PyTorch, Numba, or CuPy for custom CUDA kernels) to access the `nvcc` executable for compiling CUDA code. This package is part of NVIDIA's initiative to streamline CUDA toolkit component installation via `pip`, aiming for better portability and compatibility within the Python ecosystem. The current version is 12.9.86, and NVIDIA typically updates CUDA versions with new GPU architectures, alongside quarterly minor releases.
