George Necula f08156ab7c [hcb] Simplifications to the host_calback API
* dropping support for special AD handling for hcb.id_tap and id_print.
  From now on, only the primals are tapped. The old behavior can be
  obtained (for a limited time) by setting the JAX_HOST_CALLBACK_AD_TRANSFORMS
  environment variale, or the --flax_host_callback_ad_transforms flag.
  Additionally, added documentation for how to implement the old behavior
  using JAX custom AD APIs.

This allows us to make some significant cleanup in the internals.
