tf: Remove TF_DEBUG_RANGE, simplify internal implementation and make …

…it robust to platforms where we get different instances of the _Node structure across shared library boundaries. Also make the TF_DEBUG environment variable apply to *all* TF_DEBUG_CODES, whether or not they are registered with TF_DEBUG_ENVIRONMENT_SYMBOL. This has been the source of confusing & hard to track down bugs.

Also remove the TF_DEBUG=list feature, which doesn't make sense in a modular world such as ours.
