ci: PR Hygiene is the merge gate; CODEOWNERS carries no rules (#1039)

The PR Hygiene status now passes only when the review policy is satisfied and
is pending while anything is still waiting, so it can be required to merge.
With it required, GitHub own approval count on this branch goes to zero and
the policy is the one thing that decides: an author who owns every area they
touched needs the bots, their attestation and a green build; anyone else also
needs an owner approval.

CODEOWNERS is a file with no rules now, on purpose. A rule there had GitHub
request every owner the moment a pull request was opened, before the bots or
the author had read it. The file stays, pointing at the policy.

dashpay/stale_prs_are_bad#37 landed as 2a9705fbefd4294f490baa36f46f2b880a592502.
