iris: Extend the cache tracker to handle L3 flushes and invalidates

Most clients are L3-coherent these days.  However, there are some
notable exceptions, such as push constants, stream output, and command
streamer memory reads and writes.

With the advent of the tile cache, flushing the render or depth caches
alone are no longer sufficient for memory to become globally-observable.
For those, we need to flush the tile cache as well.  However, we'd like
to avoid that for L3-coherent clients, as it shouldn't be necessary,
and is expensive.

iris: Add an iris_is_domain_l3_coherent helper.

The render, depth, sampler, and data (HDC) caches are all coherent
with L3.  We consider OTHER_READ and OTHER_WRITE to be non-coherent,
as they're kitchen-sink domains which include non-L3-clients.

Starting with Tigerlake, the VF cache is coherent with L3 (because we
set the L3BypassDisable bit in the vertex/index buffer packets).

iris: Fix UBO cache tracking for the !indirect_ubos_use_sampler case

On Tigerlake, we use the data cache for reading indirect UBOs instead
of the sampler.  But we still use the constant cache for direct UBO
access, so unfortunately we may access it through two different domains.

To work around this, we add a new domain for pull constants (UBOs),
which will be either constant+texture or constant+data.

iris: Split out an IRIS_DOMAIN_SAMPLER_READ domain from OTHER_READ

The bulk of IRIS_DOMAIN_OTHER_READ domain usage was the 3D sampler, but
there were also a few oddball cases like command streamer reads, blitter
access, and so on.  The sampler is definitely L3 coherent, but some off
the more esoteric reads may not be, so I'd like to separate them, so
that OTHER_READ can become a non-L3-coherent kitchen-sink domain.

The sampler cases only need TEXTURE_CACHE_INVALIDATE, and can skip the
CONSTANT_CACHE_INVALIDATE we had on IRIS_DOMAIN_OTHER_READ.

iris: Use IRIS_DOMAIN_DEPTH_WRITE for read only depth/stencil.

We were using IRIS_DOMAIN_OTHER_READ for read-only depth/stencil access
in an attempt to avoid unnecessary flushing; IRIS_DOMAIN_DEPTH_WRITE
could indicate read-write access.

However, IRIS_DOMAIN_OTHER_READ is clearly the wrong domain.  Depth and
stencil data is read via the depth cache, while IRIS_DOMAIN_OTHER_READ
currently corresponds to the sampler cache and constant cache together
(although this will change in future patches).

It's unclear whether this hack was useful.  For now, just drop it and
use the correct depth cache domain, even if it's marked as read-write.

st/mesa: Transcode ASTC to BC7 (BPTC) where possible

This patch adds support for transcoding ASTC to BC7 (BPTC) and prefers
it over BC3 (DXT5) when hardware supports that format.

BC7 is a much newer format (~2009 vs. ~1999) and offers higher quality
than the older BC3 format.  Furthermore, our encoder seems to be faster.

Tapani put together a small benchmark for transcoding a 1024x1024 ASTC
texture, and switching from BC3 to BC7 improves performance of that
microbenchmark by 25% on my Tigerlake NUC (with hardware ASTC disabled
so we can test this path).  Presumably, this isn't fundamental to the
formats, but rather reflects the speed of our in-tree compressors.

So, we should use BC7 where possible.

zink/query: refactor out vk queries and allow sharing them

gallium queries have to be mapped onto multiple vulkan queries,
this can happen for two reasons.

1. primitives generated and overflow any don't map directly, and
multiple vulkan queries are needs per iteration. These are stored
inside the "starts" as zink_vk_query ptrs.

2. suspending/resuming queries uses multiple queries, these are
the "starts". Every suspend/resume cycle adds a new start.

Vulkan also requires that multiple queries of the same time don't
execute at once, which affects the overflow any vs xfb normal
queries, so vk_query structs are refcounted and can be shared
between starts. Due to this when the draw state changes, it's
simple to just suspend/resume all queries so the shared vulkan
queries get handled properly.

intel/genxml: Add SAMPLER_MODE bits for enabling Small PL on Icelake

This enables a lower power mode in the sampler hardware in certain
common scenarios.  On Tigerlake, SAMPLER_MODE is not programmable by
userspace but the kernel already sets this bit for us.

intel/genxml: Delete SAMPLER_MODE register definition on Gfx12+

While this register still exists, it's no longer a per-context register.
Instead, on Gfx12+, SAMPLER_MODE exists per dual-subslice and is
accessed as a "multicast" register, where you write control which
version is accessed by the "steering control register".

At any rate, userspace cannot write it any longer, and so there's not
much point to it existing in our genxml (which was missing most of the
fields anyway).

intel/genxml: Add new "Low Quality Filter" field on Gfx12+.

This allows the sampler to perform faster filtering of 8-bit UNORM
textures by filtering them at a different precision.  The filtering
is intended to still be OpenGL and DirectX spec compliant.

intel/genxml: Add SAMPLER_STATE::Allow Low Quality LOD Calculation field

This allows the hardware to perform a faster LOD calculation in many
simple cases.

zink: force texture barriers when performing in-renderpass clears

according to spec, a barrier is required any time the pixels of the
framebuffer are changed. since zink defers clears and runs them at
a later time, it must also be responsible for handling the required
synchronization for such operations
