If we don't, we can end up with corruption in the portion of the depth
buffer that lies outside the render area when we do a HiZ resolve at the
end. The only reason we weren't seeing this before was that all of the
meta-based clears such as VkCmdClearDepthStencilImage were internally using
HiZ so the HiZ buffer never truly got out-of-sync. If the CTS ever tested
a depth upload (which doesn't care about HiZ) and then a partial render we
would have seen problems. Soon, we will be using blorp to do depth clears
and it won't bother with HiZ so we would get CTS regressions without this.

When I initially brought up Vulkan blorp, I completely missed that this
was already factored out. There's no good reason for us to hand-roll it.

In Vulkan, we want to be able to use blorp to perform clears inside of a
render pass. If blorp stomps the depth/stencil buffers packets then we'll
have to re-emit them. This gets tricky when secondary command buffers get
involved. Instead, we'll simply guarantee that the depth and stencil
buffers we pass to blorp (if any) match those already set in the hardware.

This never mattered before because the only time we used blorp
depth/stencil only was to do HiZ operations on gen6-7. It may have worked
in that case (and maybe it didn't) but slow depth clears actually do depth
rendering so they need a valid render target.

This should now set the pipeline up properly for doing depth and/or stencil
clears by plumbing through depth/stencil test values. We are now also
emitting color calculator state for blorp operations without an actual
shader because that is where the stencil reference value goes pre-SKL.

According to the Vulkan spec 5.63.4 :
samplerAnisotropy indicates whether anisotropic filtering is supported. If
this feature is not enabled, the maxAnisotropy member of the
VkSamplerCreateInfo structure must be 1.0.
Since we already set maxAnisotropy to 16 and program the hardware according
to the VkSamplerCreateInfo.maxAnisotropy, it seems we can turn this on.
