3422a8b258 block: qcow: Add QcowDiskAsync struct stub 
Introduce the device level handle for the async QCOW2 backend.

QcowDiskAsync mirrors QcowDiskSync. It parses the image, resolves
the backing chain and wraps QcowMetadata in an Arc for sharing
across virtio queues. No trait impls yet, just the struct,
constructor, Drop and Debug.
