In this change, the return status from query pool reads for QUEUE_OPERATIONS_END_BIT_EXT are checked and skipped when not ready. To cater for correctness of any later reads, the value returned is cached and compared. Additionally, a fix is added to avoid data corruption with presentation feedback object in present timing when vector was used.
