Fix longstanding depth/stencil view issue in Vulkan. Cleans up validation.

Browse source 
We didn't specify DEPTH|STENCIL as aspects for views we rendered to,
only DEPTH. Who knows how many of the driver bugs we "found" are this.

DEPTH|STENCIL views can't be sampled though, so we create a separate
DEPTH view for that. This keeps Katamari working.
