The alignment we use doesn't matter (see the comment) but it should at
least be an alignment we can represent with the enums.

Although a user may specify a specfic tiling bit, ISL should still
prevent incompatible tiling/surface combinations.

When we initially dropped bpb in favor of bs, we accidentally didn't change

A while ago we got rid of the bits-per-block because we thought we didn't
need it. We're about to introduce some very useful 1 and 2-bit formats so
we really should be able to handle them again.

This is based on a very long set of discussions between Chad and myself
about how we should properly represent HiZ and CCS buffers. The end result
of that discussion was that a tiling actually has two different sizes, a
logical size in elements, and a physical size in bytes and rows. This
commit reworks ISL's pitch and size calculations to work in terms of these
two sizes.

We helpfully inserted a PRM quotation about how we need to use
ARRAY_PITCH_SPAN_FULL and then set it to COMPACT. Oops...

The row pitch already specifies the size of a row of elements.
Multiplying by the block height simply causes us to allocate as muc as 12
times more memory than needed for compressed textures.

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

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.
