This change allows Skia to handle transfering from the present layout.
Skia currently never changes to the present layout, though we are looking
at adding support for this in a different CL.
With this change a client can wrap a an VkImage into an SkSurface still in
the queue present layout and Skia will handle the transation to color
attachment. If a client uses this functiality they most likely will want
to immediately call wait(GrBackendSemaphore) on the SkSurface so that Skia
waits on the VkSemaphore that came from a call to vulkan aquire image before
doing any work on the wrapped VkImage.
