This change introduce the concept of planes for image & views. It
matches the planes available in new formats.
We also refactor depth & stencil support through the usage of planes
for the sake of uniformity. In the backend (genX_cmd_buffer.c) we have
to take some care though with regard to auxilliary surfaces.
Multiplanar color buffers can have multiple auxilliary surfaces but
depth & stencil share the same HiZ one (only store in the depth
plane).
Not really. HiZ has nothing to do with stencil, it's just for depth
compression. I think, in principal, I like splitting things out into
a plane array better. I never did like the way we special-cased
depth+stencil.
Oh, maybe I dreamed that...
Isn't there a requirement to put the depth & stencil into the same
buffer? Or were we just doing that to same some space?
