anv/image: Allow HiZ on input attachment-capable depth/stencil images
While an input attachment may only take on one of those two layouts,
other depth/stencil attachments that use the same image may have
HiZ-enabled layouts. Improves the average frame rate on a release
candidate of a proprietary Vulkan benchmark by 9.94% over 3 runs on my
SKL GT4.
