drm: virtgpu: Rely on the default ->best_encoder() behavior

The virtgpu output exposes a 1:1 relationship between connectors and
encoders and the driver is relying on the atomic helpers: we can drop
the custom ->best_encoder() implementation and let the core call
drm_atomic_helper_best_encoder() for us.
