refactor: Simplify VMM code to perform API action on device

[Manciukic]

Changes

• Generate virtio device ids with bindgen
• simplify code to perform a VMM action on a device as a result of an API request

        if let Some(virtio_device) = self
            .device_manager
            .get_virtio_device(TYPE_BALLOON, BALLOON_DEV_ID)
        {
            let config = virtio_device
                .lock()
                .expect("Poisoned lock")
                .as_mut_any()
                .downcast_mut::<Balloon>()
                .unwrap()
                .config();

            Ok(config)
        } else {
            Err(BalloonError::DeviceNotFound)
        }

becomes

        self.device_manager
            .with_virtio_device_with_id(
                virtio_ids::VIRTIO_ID_BALLOON,
                BALLOON_DEV_ID,
                |dev: &mut Balloon| dev.config(),
            )
            .map_err(VmmError::FindDeviceError)

by extending the existing with_virtio_device_with_id implementation (now all accesses are using this pattern).

• cleanup unused error in balloon and fixup a particular error message

Reason

I will be adding a bunch of these with_virtio_device_with_id for the virtio-mem device and this makes it simpler rather than writing the old long if branches.
