change delegation for to_read_description
This switches to_read_description to the "new normal" delegation
scheme. This one was a bit trickier than the other changes due to the
way that target_read_description handled delegation. I examined all
the target implementations of to_read_description and changed the ones
returning NULL to instead delegate.

* arm-linux-nat.c (arm_linux_read_description): Delegate when
needed.
* corelow.c (core_read_description): Delegate when needed.
* remote.c (remote_read_description): Delegate when needed.
* target-delegates.c: Rebuild.
* target.c (target_read_description): Rewrite.
* target.h (struct target_ops) <to_read_description>: Update
comment. Use TARGET_DEFAULT_RETURN.
