order to support depth/stencil surfaces and multisampling. Create new
ISL enums and define some initial tiling information in order to enable

This is mostly a bit of future-proofing. We never end up with offsets
that don't fit in 32 bits today because, thanks to driver limitations
caused by relocations, we don't allocate buffers bigger than 2GB today.
However, if we ever did, it's possible to create a surface on modern
platforms that consumes more than 4GB and we would end up with wrapping
in our offset calculations.

This adds a helper isl_surf_get_uncompressed_surf for creating a surface
which provides an uncompressed view into a compressed surface. The code
is basically a direct port of the uncompressed surface code from the
Vulkan driver which, in turn, was a port from BLORP.

XeHP adds support for a new surface type for scratch. It's similar to
SURFTYPE_STRBUF in that it's a 2D array-of-struct format but the one
key difference is that the U coordinate is computed automatically based
on the thread ID and only the V coordinate is provided in the dataport
message.

This gets rid of the awkward interface for isl_surf_get_ccs_surf where
we passed it two aux surfaces and it was supposed to fill out the second
one based on whether or not the first one already had stuff in it.
Instead, we now pass it three well-labled surfaces: surf,
hiz_or_mcs_surf, and ccs_surf which have obvious meanings. This does
mean that iris has to carry a bit of logic and we have to flip
parameters around in all the callers. But the resulting interface is
much cleaner.

Whether or not a surface supports CCS on Tigerlake and later is
dependent not only on the main surface but also on the MCS or HiZ
surface, if any. We were doing some of these checks in
isl_get_ccs_surf based on the extra_aux parameter but not as many as we
probably should. In particular, we were really only checking HiZ
conditions and nothing for MCS. It also meant that, in spite of the
symmetry in names, the checks in isl_surf_get_ccs_surf were more
complete than in isl_surf_supports_ccs.

Thanks to Felix Degrood for discovering that we missed enabling this
additional caching on Tigerlake! Felix also benchmarked the changes.
We now use MOCS 48 (HDC:L1 + L3 + LLC) for render targets, textures,
and pull constant buffers. We leave storage buffers & images, as well
as stateless messages, using the previous MOCS 2 value. We can't use
HDC:L1 with atomics, and we don't know a priori whether storage buffers
will be used with atomics or not. Similarly, the Vulkan buffer device
address feature allows atomics to be performed on buffers via stateless
messages, and we only can control MOCS at the base address level, so
we can't do much there.
This is closer to what the Windows Vulkan and OpenGL drivers do,
though it isn't quite the same - they also disable LLC in some cases,
but we observed this to have noticable performance regressions when
we tried (though a couple titles benefited). We may try experiment
with that in the future.
Improves performance in a number of titles:
- Unreal Engine 4 Shooter Demo [VK]: 11.8%
- Witcher 3 [DXVK]: 3.9%
- Rise of the Tomb Raider [VK]: 1.5%
- Shadow of the Tomb Raider [VK]: 1.0%
- Grand Theft Auto V [DXVK]: 0.8%
We did not observe any performance regressions.

On Gen12+, we can enable additional caches in certain usage situations.
This routes that decision making to a central place in ISL, based on
surface usage flags, and updates both drivers to use it. (i965 doesn't
need to change because it doesn't support Gen12.)
We continue handling the "external" decision via an anv_mocs() wrapper
for now, since we store that flag in anv_bo, which isl doesn't know
about. (We could introduce an ISL_SURF_USAGE_EXTERNAL, but I'm not
actually sure that would be cleaner.)
This patch should not have any functional nor performance effects, as
we continue selecting the exact same MOCS values for now.
