ISL was being a bit too clever for its own good and lowering the format for
us. This is all well and good *if* we always want to lower it. However,
the GL driver selectively lowers the format depending on whether the
surface is write-only or not.

This field is ignored by the hardware in this case and, on very large 1-D
textures, it can end up being larger than the maximum allowed value.

This matches better what happens on gen8 where the "Tiled Surface" and
"Tile Walke" bits are combined into a single two-bit value. This is also
more consistent with what the GL driver does.

For depth/stencil 1-D textures on SKL, we want them layed out in the old
format that has been used since gen4. In order for the surface state
fill-out code to handle, this it needs to distinguish based on layout
rather than just dimensionality.

The docs specify that this only matters for render targets and surfaces
used with typed dataport messages. On some platforms (gen4-6) the Depth
field has more bits than RenderTargetViewExtent so we can have textures
with more levels than we can render to.

According to the PRM, you can't set SurfaceArray for 3D or buffer textures.
There doesn't seem to be a good reason not to set it when we can. On the
other hand, if we don't set it we can end up getting strange results for
1-layer array textures such as textureSize() returning the wrong results.

We already set the bit in the few cases where it's required by the docs so
there's no need to set it all the time. This has no noticable perf impact
for Dota 2 on Vulkan with the time demo I have.

This commit switches clear colors to use #if's instead of a C if. This
lets us properly handle SNB where the clear color field doesn't exist.

This moves the #if's around so that halign and valign have different sets
of #if conditions. This also prepares us for SNB because isl_to_gen_halign
is not defined at all on gen6.

While designated initializers are nice, they also force us to put some
things in the initializer and some things later. Surface state setup is
complicated enough that this really hurts readability in the long run.

We want to call this function from the shader compiler and having a full
isl_device available at that point isn't practical.
