Add a new option `--cuda` to `tools/nightly.py` to pull the nightly packages with CUDA support.
```bash
# installs pytorch-nightly with cpuonly
tools/nightly.py pull
# The following only available on Linux and Windows
# installs pytorch-nightly with latest CUDA we support
tools/nightly.py pull --cuda
# installs pytorch-nightly with CUDA 12.1
tools/nightly.py pull --cuda 12.1
```
Also add targets in `Makefile` and instructions in constribution guidelines.
```bash
# setup conda environment with pytorch-nightly
make setup-env
# setup conda environment with pytorch-nightly with CUDA support
make setup-env-cuda
```

Building with CUDA in dev container leads to error: `cannot find -lcudart_static`. This is because the libraries are under a custom CUDA_HOME, and `ld` cannot find it.
Updating the `LDFLAGS` environment variable works.
