Auto merge of #54530 - pnkfelix:issue-54047-migrate-ui-run-pass-back-to-run-pass, r=alexcrichton

Migrate `src/test/ui/run-pass/*` back to `src/test/run-pass/`.

Moves all the tests from `src/test/ui/run-pass/**` back to `src/test/run-pass/`.

This should have no impact on our overall testing completeness due to PR #54223

Fix #54047
