Revamp TorchBench nightly image build process (#2635)
Summary:
Notable changes:
1. Use NVIDIA image `nvidia/cuda:${CUDA_VERSION}-devel-ubuntu22.04` as the base so that we don't need to setup CUDA
2. Replace `conda` with `uv`
3. Cleanup unused code path
4. Unpin TIMM and transformers to get their latest stable version
