Summary	0005077: Vulkan validation error related to VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_KMT_BIT
Description	Validation Error: [ VUID-VkMemoryAllocateInfo-memoryTypeIndex-00645 ] \| MessageID = 0xb4ec2301 vkAllocateMemory(): pAllocateInfo->memoryTypeIndex is 1 but VkMemoryWin32HandlePropertiesKHR::memoryTypeBits is 0x0 with handleType VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_KMT_BIT. The Vulkan spec states: If the parameters define an import operation and the external handle is an NT handle or a global share handle created outside of the Vulkan API, the value of memoryTypeIndex must be one of those returned by vkGetMemoryWin32HandlePropertiesKHR (https://docs.vulkan.org/spec/latest/chapters/memory.html#VUID-VkMemoryAllocateInfo-memoryTypeIndex-00645) No good and consistent repro steps yet.
