This cleans up the activate() signature and avoids the need to pass two
related (Queue, Event) variables everywhere a queue is needed.
No functional change intended.

Now that an active Queue is a separate type than the pre-activation
QueueConfig, we can ensure that a Queue has a valid reference to the
GuestMemory at creation time instead of passing it to every queue
operation.
No functional change, but simplifies Queue callers and prepares for
use of AtomicU* types in a later change.

To support packed virtqueue in block device, add packed-queue runtime
flag to block device. If flag is set true, block deivice uses packed
virtqueue. If flag is not set or set to false, block device use split

This change creates a new type (QueueConfig) that represents a queue
configuration before it has been activated. The QueueConfig::activate
function serves the same purpose as the previous Queue::activate, but
now it also returns the Queue type, which now always represents an
actively running queue.

Previously, devices used the split virtqueue implemented in
/src/virtio/queue.rs by default. In order to support packed virtqueue in
the future, we implemented the enum type for virtqueue to abstract over
different virtqueue types. We migrated existing split virtqueue to a new
mod in /src/virtio/queue/ directory.
To support different types of virtqueue for each device, we enhanced
virtio_device trait by defining queue_type method to decide which
virtqueue type the device should use. We also modified base_feature function to accept queue type as a parameter.
