This CL implements the MemoryService for importing memory and creating VkImages from a dma-buf handle. Under the hood, it uses the VK_EXT_external_memory_dma_buf and VK_EXT_image_drm_format_modifier extensions to find a memory type that supports dma-buf import. In addition, the extensions are also used to properly specify the stride and tiling of the dma-buf to vkAllocateMemory and vkCreateImage.
