Add CreateImage support to MemoryService

This CL introduces SupportsCreateImage and CreateImage to the
external memory service API to provide different implementations for
creating VkImages for different types of external image handles.

While opaque FD and Zircon seem to share the same vkCreateImage
implementation, dma-buf import will require the use of the
VkImageDrmFormatModifierExplicitCreateInfoEXT [1] struct (among
other differences) with vkCreateImage.
