freedreno/a6xx: Add support for polygon fill mode (as long as front==back).
Unlike a4xx, we don't seem to have separate back vs front fields any more. Still, this improves desktop GL conformance (and one of the traces in traces-db). Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5650>
