Subject: [PATCH] Migrate winforms-pr internal-feed auth to System.AccessToken

The winforms-pr pipeline (eng/pipelines/build-PR.yml) authenticated internal darc-int-* feeds with the dn-bot-dnceng-artifact-feeds-rw PAT, which was removed from the arcade secret manifest and expired 2026-07-11. This causes HTTP 401 on Arcade SDK toolset restore in internal/release/8.0 PR/CI builds. Switch to $(System.AccessToken) (build identity), mirroring eng/pipelines/build.yml on the same branch.
