In Vk DeferredLayerUpdater make sure we releause buffers to foreign queue.

For Vulkan we need to make sure that when we draw AHBs we must
transition them to and from the foreign queue so that the producer is
able to write new data to them and we are able to see the new writes.

Test: Manual running of Lens app
