Benjamin Otte e7549f3359 vulkan: Redo barriers
We now store all the relevant state of the image inside the VulkanImage
struct, so we can delay barriers for as long as possible.

Whenever we want to use an image, we call the new
gsk_vulkan_image_transition() and it will add a barrier to the desired
state if one is necessary.
