Remove Clair Obscur: Expedition 33 from the collection

The game supports ultrawide natively, so there is nothing for this project to
fix. Deletes games/Expedition33 and all references (README table, THIRD_PARTY,
the never-published v1.2.0 changelog section). A one-line changelog note records
why it was dropped, and the METHOD=native tooling capability stays for any
future works-out-of-the-box title.
