NVIDIA cuDNN Runtime Libraries for CUDA 12

The `nvidia-cudnn-cu12` package provides the NVIDIA CUDA Deep Neural Network (cuDNN) runtime libraries, which are GPU-accelerated primitives essential for deep neural network operations such as convolutions, attention, and matrix multiplication. It acts as a critical low-level dependency, enabling deep learning frameworks like TensorFlow and PyTorch to efficiently leverage NVIDIA GPUs. This specific package targets CUDA 12.x environments. The current version is 9.20.0.48, with releases frequently updated to align with new CUDA Toolkit versions and cuDNN backend enhancements.
