according to KHR_gl_texture_3D_image:
If <target> is EGL_GL_TEXTURE_3D_KHR, <buffer> must be the name of a
complete, nonzero, GL_TEXTURE_3D (or equivalent in GL extensions) target
texture object, cast
into the type EGLClientBuffer. <attr_list> should specify the mipmap
level (EGL_GL_TEXTURE_LEVEL_KHR) and z-offset (EGL_GL_TEXTURE_ZOFFSET_KHR)
which will be used as the EGLImage source; the specified mipmap level must
be part of <buffer>, and the specified z-offset must be smaller than the
depth of the specified mipmap level.
thus a 2d view of a 3d surface is not only legal, it's part of the spec and
must be supported when available

We're going to start programming this field for media compression, so

On XeHP, the XY_BLOCK_COPY_BLT command has a number of fields that
describe the layout of the surface, much like SURFACE_STATE does.
Several of them are encoded in such a similar manner that we really
would like to reuse the isl helpers for emitting those. This commit
moves them into a new isl_genX_helpers.h file which I can include
from the BLORP code. (The alternative would be to add XY_BLOCK_COPY_BLT
filling commands to isl, but that...seems more like a BLORP feature.)

The sampler can only decode ASTC surfaces that are Y-tiled. ISL has
been asserting this restriction at surface creation time.
However, some drivers want to create a surface that is only used for
copying compressed data. And during the copy, the surface won't have a
compressed format.
To enable this behavior, we choose to move the tiling assertion to the
moment a surface state is created for the sampler.

We'd like to add safeguards against accidental use of MOCS 0 (uncached),
which can have large performance implications. One case where we use
MOCS of 0 is SURFTYPE_NULL surfaces, where MOCS really shouldn't matter,
as there's no actual surface to be cached.
That said, it should be harmless to set MOCS for these null surfaces;
we can just assume a generic MOCS for internal buffers.

In ISL, usage flags only carry intent and not semantic meaning. We
don't have a bulletproof way in ISL to specify that an image is of
depth/stencil type. The usage flags are great but blorp, for instance,
loves to disrespect them. One proposed solution to this problem is to
add explicit depth/stencil formats which are distinct from the
corresponding color formats.
Fortunately, however, empirical evidence suggests that this bit only
affects the sampler's interpretation of the CCS data. Therefore, we can
set the bit based off of the aux_usage which is now very specific and
does carry semantic meaning. In particular, aux_usage now makes a
distinction between color CCS and depth/stencil CCS which appears to be
exactly what the DepthStencilResource bit is for.

Stencil CCS is slightly different from color CCS. Using a color CCS
resolve with stencil CCS doesn't do the right thing and you can't sample
from a stencil CCS image without the DepthStencilResource bit set or you
will get the wrong data. Stencil CCS also has it's own rules such as it
doesn't support fast-clear and has no partial resolve. This seems to
indicate that it should probably be its own isl_aux_usage. Now that
adding new isl_aux_usage values is pretty cheap, let's split stencil CCS
out on its own.

We also delete the badly named isl_surf_supports_hiz_ccs_wt. The name
is misleading because it doesn't return whether or not the surface
supports HiZ+CCS in write-through mode (any single-sampled HiZ+CCS
capable surface does) but rather a heuristic decision about whether or
not we want to enable write-through mode based on the usage flags in the
isl_surf.

This is distinct from ISL_AUX_USAGE_HIZ_CCS in that the HiZ surface
operates in write-through mode which means that the HiZ surface is only
used for depth-testing acceleration and the CCS-compressed main surface
is always valid so we can texture from it.
Separating full HiZ from write-through mode at the isl_aux_usage level
has a couple of advantages:
1. It's more explicit. Instead of write-through mode depending on the
heuristic decision in isl_surf_supports_hiz_ccs_wt, it's now
something that's explicitly requested by the driver. This should be
more robust than hoping isl_surf_supports_hiz_ccs_wt always returns
the same thing every time. If someone (say BLORP) ever drops a
usage flag on the isl_surf, there's a chance it could return a
different value without us noticing leading to corruptions.
2. Because ISL_AUX_USAGE_HIZ_CCS_WT is it's own isl_aux_usage flag, we
can say inside the driver that HIZ_CCS does not support sampling but
HIZ_CCS_WT does. We can also pass HIZ_CCS_WT to isl_surf_fill_state
and it can do some validation for us beyond what we would be able to
do if we conflate HIZ_CCS_WT and CCS_E.
3. In the future, we can add new heuristics to the driver which do
things such as start all depth surfaces (regardless of usage flags)
off in HIZ_CCS and then do a full resolve and drop to HIZ_CCS_WT the
first time it gets used by the sampler. This would potentially let
us enable the faster HIZ_CCS mode even in cases where it technically
comes in through the API as a texture.

The second check involves an exclusion list of things which don't have
