be5e160c - Remove executorch from all-latest-gpu image + add torch smoke test (#47196)

Remove executorch from all-latest-gpu image + add torch smoke test (#47196) Fix nightly all-latest-gpu image: drop executorch, add torch smoke test executorch is a CPU-only export dependency. In the GPU image its version constraint (executorch 1.3.1 requires torch>=2.12) uninstalls the pinned cu126 torch and pulls a torch on a different CUDA/NCCL stack, breaking the whole image with `undefined symbol: ncclCommResume` at `import torch` (nightly failures). Remove executorch from the GPU image (it moves to the CPU torch-light image) and add a build-time torch smoke test that fails the build immediately if a later pip install clobbers the pinned CUDA torch. Keep onnxruntime-gpu for GPU-accelerated ONNX export validation.
