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.

st/mesa: Make transcode_astc also check for non-SRGB format support

This is probably unnecessary in that all drivers which support the sRGB
format likely also support the non-sRGB format.  But we may as well
check both the formats we use, for documentation if nothing else.
