Advertise VIRTIO_VSOCK_F_DGRAM and record whether the device
negotiated it. Gate datagram socket initialization and destination
checks on the negotiated feature and the transport's supported network
namespace mode.
Perform device capability checks at socket creation without requiring
a remote address, which is not yet known for an unconnected datagram
socket. The common virtio implementation provides the datagram data
path.
