devlink: cleanups and move devlink health functionality to separate file

This patchset moves devlink health callbacks, helpers and related code
from leftover.c to new file health.c. About 1.3K LoC are moved by this

In addition this patchset includes a couple of small cleanups in devlink
health code and documentation update.
