**Backport:** https://codeberg.org/forgejo/forgejo/pulls/13215
Followup of the refactor adding setter/getter to APIContext https://codeberg.org/forgejo/forgejo/pulls/13143
- Only has an impact on the getters used by `routers/api/v1/permissions`
- When GetX and X both exist, remove GetX
- When GetX exists and X does not, rename GetX to X
- GetOrg is an exception as it would conflict with Org and is renamed Organization. This is due to APIContext having its own Org structure that includes an Organization.
