Since we run "cargo clean" before running the aarch64 build we need to
create the release and upload the x86-64 assets before the clean.

Adjust the release workflow to move the conditional check on the tag
creation into the steps that create the release/upload the assets.
This allows us to ensure we're always in a releaseable state.

This change is important to do a proper resource cleanup. We decided
to do this repetitive approach as VirtioCommon can't implement Drop
without major changes to the corresponding code. Also, devices such as
Net can't easily use the epoll_threads-abstraction from VirtioCommon as
it has multiple threads with different semantics.

For the synchronous backends efficiently preserve the order for
completion requests through the use of VecDequeue. Preserving the order
is not required but is beneficial as it matches the existing
optimisation that looks to match completions and requests.

Rather than aggregate the completion list into an intermediate vector
instead adjust the API to provide one completion item at a time.
With DHAT this shows the number of heap allocations has decreased.

The number of buffers in the request is usually one so by using SmallVec
the number of heap allocations can be significantly reduced.

Rather than passing the vector of iovecs for the I/O to act on pass a
reference to the slice of values inside them. This removes the explicit
container type from the API allowing the use of e.g. SmallVec.

The number of entries in the refcount table was incorrectly calculated
given there was no need for dividing the number of refblock clusters.
The number of refblock clusters is the number of entries in the refcount
table.

During analysis of the asynchrous block I/O handling it was observed
that the majority of the time the completion events occur in the same
order as submissions. Further the maximum number of inflight requests
during the boot time is much lower than the size of the queue.
Through the use of a double ended queue (VecDequeue) with a reasonable
pre-allocation capacity we can have O(1) allocation free addition of
items to the list of inflight requests and mostly O(1) matching of
completed requests to submissions.

When using DHAT[1] for analysis the amount heap allocations change from:
dhat: Total: 3,186,536 bytes in 41,452 blocks
to
dhat: Total: 1,059,816 bytes in 34,747 blocks
When running against virtio-block; this still more allocations than
virtio-pmem but a significant improvement without any cost.
