Ryan Neph d5fa537753 rutabaga_gfx: avoid fence_poll() if all components use async_fence_cb ... An optional performance optimization that almost completely avoids the wakeup cost of timer-based fence polling when all RutabagaComponents use async_fence_cb. There is still a small overhead from the per-loop virtio_gpu.needs_fence_poll() tests. This overhead will be removed in later CLs, when timer-based fencing support is removed.
