fix: vastly superier handling of queue chunks (#2461)

- remove ChunkHolder locking concept as this is no longer needed
 - previously we obtained the copy from chunk GET on finalize, meaning the copy could be replaced by a "newer" one (bad)
 - work around this issue by introducing concept of "unique" keys to map chunk GET copies to
 - correctly handle resetting of various chunk-related classes to actually allow pooling to work
 - remove chunks as they are submitted when flushing a SingleThreadQueueExtenting
