The QEMU community has broad consent to not accept assisted-by and similar
trailers, and much less fake co-authored-bys, independent of any AI policy.
Implement this in checkpatch.pl already, so that there is another way for
contributors to discover the AI policy.

Few years ago Peter was concerned about using non-ASCII because
it was not displaying correctly on his terminal:
https://lore.kernel.org/qemu-devel/cafeaca-cjwce9k+tqq-vdrevzzpv_+cxar1j9qfr_ivjtj3...@mail.gmail.com/
(that was using Ubuntu 22.04 which we don't support anymore).
Should we still worry about non-ASCII in the repository? Having
a quick look at the OS versions we support it seems all of them
are ready to handle UTF-8 chars. Anyway I saw various utf-8
emoji symbols in gitlab issues, and it is likely someone will
paste one along with the report when filling commit description
for a fix, so they'll end up displayed in a terminal via git-log.
