Greg Daniel cb32415753 Add support for VK_IMAGE_LAYOUT_PRESENT_SRC_KHR in skia vulkan.
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.
