Stefano Garzarella b113dc6b28 sound: promote to main workspace

The current implementation seems ready to be promoted to the
main workspace since the device supports both playback and recording,
and several audio backends.

Also, test coverage is good and aligned with the coverage of crates
in the main workspace.

   A virtio-sound device using the vhost-user protocol.

Options

     --socket <SOCKET>
            vhost-user Unix domain socket path

     --backend <BACKEND>
            audio backend to be used [possible values: null, pipewire, alsa]

With QEMU, you can add a virtio device that uses the backend's socket with the following flags:

-chardev socket,id=vsnd,path=/tmp/snd.sock \
-device vhost-user-snd-pci,chardev=vsnd,id=snd
