anv/wsi: Throttle rendering to no more than 2 frames ahead
Right now, Vulkan apps can pretty easily DOS the GPU by simply submitting a
lot of batches. This commit makes us wait until the rendering for earlier
frames is comlete before continuing. By waiting 2 frames out, we can still
keep the pipe reasonably full but without taking the entire system down.
This is similar to what the GL driver does today.
