* Acquire the Vulkan queue backing a command queue.

* While a queue is acquired by the client, it is locked so that
* neither the vkd3d library nor other threads can submit work to
* it. For that reason it should be released as soon as possible with
* vkd3d_release_vk_queue(). The lock is not reentrant, so the same
* queue must not be acquired more than once by the same thread.
*
* Work submitted through the Direct3D 12 API exposed by vkd3d is not
* always immediately submitted to the Vulkan queue; sometimes it is
* kept in another internal queue, which might not necessarily be
* empty at the time vkd3d_acquire_vk_queue() is called. For this
* reason, work submitted directly to the Vulkan queue might appear to
* the Vulkan driver as being submitted before other work submitted
* though the Direct3D 12 API. If this is not desired, it is
* recommended to synchronize work submission using an ID3D12Fence
* object, by submitting to the queue a signal operation after all the
* Direct3D 12 work is submitted and waiting for it before calling
* vkd3d_acquire_vk_queue().
