Add explicit CUDA version suffix to GPU release artifacts (#28691)
### Description
For ORT 1.27, GPU release artifacts (zip/tgz) now include an explicit
CUDA major version suffix to distinguish between CUDA 12 and CUDA 13
builds.
**Before:** `onnxruntime-linux-x64-gpu-1.27.0.tgz`,
`onnxruntime-win-x64-gpu-1.27.0.zip`
**After:** `onnxruntime-linux-x64-gpu_cuda12-1.27.0.tgz`,
`onnxruntime-win-x64-gpu_cuda13-1.27.0.tgz`, etc.
