Vulkan: Free the garbage memory before realloc Currently image allocations fall back to system memory in case of a device OOM. However, in some cases, it is also possible to gain some memory by freeing garbage memory from the device. This allows us to keep the allocation on the device memory. * Updated the image allocation fallback, so we will try cleaning the garbage memory through the renderer before retrying the allocation. * finishOneCommandBatchAndCleanup() in RendererVk, which will call a similar function in its CommandQueue. It will be called until there are no more in-flight submissions. * The existing finishOneCommandBatchAndCleanup() in CommandQueue has been renamed to finishOneCommandBatchAndCleanupImpl(). * Updated the flags used for VMA image allocations. If any device memory is freed after garbage cleanup to make enough space for the new allocation, it will take precedence over the system memory. * Added unit tests in which a new image allocation could happen on the device after freeing the garbage memory. * They use a 2D texture and a 2D texture array for garbage.
