This actually was already the minimum version since we build with that version, but we needed to tighten the constraints.
Also in passing, drop mentions of CUDA builds from the Windows build instructions. jaxlib hasn't built with CUDA enabled on Windows for a very long time, so it's probably best we just don't mention it.

* Make jaxlib a direct dependency of jax.
* Remove mentions of monolithic CUDA installations from the JAX documentation.
* Drop the cuda12_pip extra and the cudnn version specific extras.
* Add a with_cuda extra to the jax-cuda12-plugin package, use it in jax's setup.py. This allows us to specify cuda extras in one place.
* Make a few small doc improvements.
With this change, existing plugin discovery mechanism can discover local plugins without pip install.
Update jax_plugins/cuda/__init__.py to return without registering the plugin if the .so file does not exist.
