The `group()` helper creates the new builder "relative" to the existing
one, so this was resulting in some uniform instructions having
a non-zero channel offset ("group") -- which was surprising and had no
practical effect.
Normalize to always use group = 0. No change in behavior expected.

It was already computed in brw_shader::assign_curb_setup() so we can use it
in brw_assign_urb_setup().
There was a mismatch between assign_curb_setup() and brw_assign_urb_setup() when
push_sizes were not multiple of REG_SIZE, the first one was aligning every
push_sizes before sum it, while brw_assign_urb_setup() was only aligning the sum
of all push_size.
By luck the only places that did not had a push_size aligned to REG_SIZE only
had one push_size, so this was not an issue.
So here also fixing this mismatch and adding an assert to caught any future
mismatch.

VK_FORMAT_{R8G8B8,B8G8R8}_{UNORM,SRGB} describe a 3-component, 8bpc,
24bpp, format. This is mapped to that type for Android, and implemented
as such by panvk. radv maps these to 4-component/32bpp formats, but only
support these formats for buffers rather than images. The outlier is
ANV, which relies on the 24->32bpp mapping to happen.
The Wayland WSI was mapping this to the 32bpp R8G8B8A8/B8G8R8A8 formats
instead. This would cause a failure to import the dmabuf into the
compositor on panvk, as it would send a buffer which was too small. (Or,
if it did import: garbage.)

In elk, we tried to store our own "driver" enum values after Mesa's
VARYING_SLOT_MAX. In brw, we eliminated all of these except for an
unnecessary "BRW_VARYING_SLOT_PAD" value. This was used for empty
slots, so vue_map::slot_to_varying[] could store something. This
patch replaces BRW_VARYING_SLOT_PAD with -1.
Our "driver" enum values overlapped with VARYING_SLOT_PATCH0, leading
to unnecessary headaches. Now gl_varying_slot_name_for_stage will do
the right thing for both regular and patch varyings.

This drops native support for legacy GL's two-sided color feature
in favor of lowering it via nir_lower_two_sided_color(). Instead
of having a whole bunch of state management hassle to set up the
SBE unit to swizzle between the COL and BFC VUE slots, and have it
transparently deliver one or the other to the fragment shader, we
simply deliver both and insert a conditional select there:
(is-front-facing ? front color : back color)
This also works even for > 16 varyings, where swizzling via the SBE
unit isn't viable.
zink, asahi, freedreno, lima, panfrost, r600, v3d, and vc4 all use
this lowering rather than having native support. Only four games in
our shader-db even use this feature.

iris decides to do recompiles or not based on its own program keys,
not the brw or elk keys. So, it makes sense to handle the "why did
we have to recompile a new variant" debugging based on those keys as
well. It also unifies the code, eliminating a brw/elk split, so it's
actually less code.
Additionally, this was the only remaining user of the brw code, so we
can delete that, resulting in even larger cleanups.

This is always set to true for elk platforms. No need for the option.
crocus also assumes that we take the sampler path. hasvk had support
for both paths (leftover from when the driver still supported Gfx12).
We started using HDC messages for indirect UBO access on Tigerlake
(Gfx12.x) because of cache reworks that made it more viable. On all
prior platforms, we used the sampler because it has additional L1/L2
caches that the dataport lacks. Additionally, Ivybridge and nearby
platforms had notoriously slow L3 access in some very common cases.
Note that we do use the dataport for constant-offset UBO access,
since we can combine many reads into larger block loads.
