The token a request authenticated with now lives on the doer, so
permission and visibility checks apply its scope from the doer alone.
Replaces https://github.com/go-gitea/gitea/pull/39167, following
https://github.com/go-gitea/gitea/pull/39167#issuecomment-6063839619.
1. Public-only tokens get 404 instead of 403 for hidden users, orgs and
repos, like GitHub.
2. Org ownership, site admin, repo and org creation, generation and
transfer endpoints reject public-only tokens.
3. API pull request responses set `head.repo` to `null` and
`head.repo_id` to `-1` when the caller cannot see the head repository.
4. Public-only tokens see org memberships like anonymous callers, so
concealed members stay hidden.
5. Site admin access in activity feeds, follower lists, org members,
Actions run lists and packages needs a session or an `all`-scoped token.

Admin and write team authorize now grant that mode on every unit,
including units added later, instead of only rows present in
`team_unit`. Granular teams keep `authorize=none` and explicit unit
rows.
Closes the `TEAM-UNIT-PERMISSION` design gap from
https://github.com/go-gitea/gitea/pull/34128.
Maybe also fix#15962 (actually maybe it had been fixed before, the root
cause is out-of-sync "access" table)
