docs: stable-kernel-rules: create special tag to flag 'no backporting'

Document a new variant of the stable tag developers can use to make the
stable team's tools ignore a change[1].

That way developers can use 'Fixes:' tags without fearing the changes
might be backported in semi-automatic fashion. Such concerns are the
reason why some developers deliberately omit the 'Fixes:' tag in
changes[2] -- which somewhat undermines the reason for the existence of
that tag and might be unwise in the long term[3].

There furthermore is a variant of the stable tag you can use to make the stable
team's backporting tools (e.g AUTOSEL or scripts that look for commits
containing a 'Fixes:' tag) ignore a change::
