When performing preview job rendering the memory wasn't recycled leading to a memory leak. For background rendering we already recycled memory in a correct way. This change enables the same branch during preview rendering. Also adds a better `VKDevice::debug_print` to see the resources being tracked by the different threads and resource pools.
