My motivation here is to fix the plugin support for batch partitionable custom calls. Since plugin support for custom call partitioners is provided via register_plugin_callback in xla_bridge, instead of xla_client itself, it's much more straightforward to register the custom calls in JAX. It would be possible to refactor things differently, but it actually seems like a reasonable choice to use the supported APIs from `jax.ffi` instead of `xla_client` so that we can take advantage of any new features we might add there in the future. This is all still a little bit brittle and I'd eventually like to migrate to a version where the XLA FFI library provides a mechanism for exporting handlers, but this change is still compatible with any future changes like that.

jaxlib: support library for JAX
jaxlib is the support library for JAX. While JAX itself is a pure Python package, jaxlib contains the binary (C/C++) parts of the library, including Python bindings, the XLA compiler, the PJRT runtime, and a handful of handwritten kernels. For more information, including installation and build instructions, refer to main JAX README: https://github.com/jax-ml/jax/.
