 * cost of resource creation across multiple command buffers. Command pools are externally synchronized, meaning that a command pool must
 * not be used concurrently in multiple threads. That includes use via recording commands on any command buffers allocated from the pool,
 * as well as operations that allocate, free, and reset command buffers or the pool itself.

 * vkQueueSubmit is a queue submission command, with each batch defined by an element of pSubmits as an instance of the VkSubmitInfo structure.
 * Batches begin execution in the order they appear in pSubmits, but may complete out of order.
 * Fence and semaphore operations submitted with vkQueueSubmit have additional ordering constraints compared to other submission commands,
 * with dependencies involving previous and subsequent queue operations. Information about these additional constraints can be found in the semaphore and
 * fence sections of the synchronization chapter.
 * Details on the interaction of pWaitDstStageMask with synchronization are described in the semaphore wait operation section of the synchronization chapter.
 * The order that batches appear in pSubmits is used to determine submission order, and thus all the implicit ordering guarantees that respect it.
 * Other than these implicit ordering guarantees and any explicit synchronization primitives, these batches may overlap or otherwise execute out of order.
 * If any command buffer submitted to this queue is in the executable state, it is moved to the pending state. Once execution of all submissions of a command buffer complete,
 * it moves from the pending state, back to the executable state. If a command buffer was recorded with the VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT flag,
 * it instead moves back to the invalid state.
 * If vkQueueSubmit fails, it may return VK_ERROR_OUT_OF_HOST_MEMORY or VK_ERROR_OUT_OF_DEVICE_MEMORY.
 * If it does, the implementation must ensure that the state and contents of any resources or synchronization primitives referenced by the submitted command buffers and any semaphores
 * referenced by pSubmits is unaffected by the call or its failure. If vkQueueSubmit fails in such a way that the implementation is unable to make that guarantee,
 * the implementation must return VK_ERROR_DEVICE_LOST. See Lost Device.
