Subject[PATCH] configs/debug: add NET debug config
The debug.config file is really great to easily enable a bunch of
general debugging features on a CI-like setup. But it would be great to
also include core networking debugging config.

A few CI's validating features from the Net tree also enable a few other
debugging options on top of debug.config. A small selection is quite
generic for the whole net tree. They validate some assumptions in
different parts of the core net tree. As suggested by Jakub Kicinski in
[1], having them added to this debug.config file would help other CIs
using network features to find bugs in this area.

Note that the two REFCNT configs also select REF_TRACKER, which doesn't
seem to be an issue.

Notes:
- It looks like this debug.config doesn't have a specific maintainer.
If this patch is not rejected, I don't know if this modification can
go through the net tree, or if it should be handled by Andrew.
Probably the latter? I didn't add [net-next] in the subject for this
reason.
