viable/strict/1791882163: [Windows] Depend on PyPI CUDA runtime packages in wheels (#194056)

发生了什么

Summary This PR teaches Windows PyTorch CUDA wheels to locate their CUDA runtime DLLs from installed NVIDIA PyPI packages (via cuda-pathfinder) rather than bundling them inside torch/lib/. It adds per-OS wheel dependency metadata, updates the build matrix generator, adjusts CMake to skip bundling when using PyPI-sourced runtimes, and adds a Windows smoke test that validates the declared cuda-toolkit version matches…
