The BROADCOM_SAND128 modifier is usually used with an extra parameter
to pass in the stride via a side channel. Quoting from drm_fourcc.h:
> The pitch between the start of each column is set to optimally
> switch between SDRAM banks. This is passed as the number of lines
> of column width in the modifier (we can't use the stride value due
> to various core checks that look at it , so you should set the
> stride to width*cpp).
So apparently this is just a workaround for limitations in some kernel
APIs. DRM modifiers, however, are arguably a bad fit for extra
parameters that aren't known in advance. In the Wayland/KMS ecosystem
many components depend on being able to treat modifiers as opaque, e.g.
for negotiations etc. In practice the current approach requires various
software components to manually use the
`DRM_FORMAT_MOD_BROADCOM_SAND128_COL_HEIGHT()` macro - using the
`DRM_FORMAT_MOD_BROADCOM_SAND128` modifier directly with formats like
`NV12` results in a rejection in the KMS driver and corrupted output
in Mesa (because we'd bail out early in `v3d_sand8_blit()`).
Fortunately the stride check limitations mentioned above don't seem to
apply to Mesa though. Thus we can just add support for the base modifier
and stride (coming from V4L2), allowing various toolkits, Wayland
compositors and V4L2 decoder implementations to support e.g.
`NV12` + `DRM_FORMAT_MOD_BROADCOM_SAND128` (`NC12` in V4L2) in a generic
way.
Notes:
1. Wayland compositors trying to offload composition to KMS will still
fail when doing a test commit.
2. There is another limitation - in the V4L2 MPLANE API - that
requires userspace to know the correct offset of the second plane. That's
a known API limitation though and only affects V4L2 decoder implementations.

Since the shader parameters are passed as inline data, push constants
are no longer used and so, not actually set on dispatch. But the
nr_params = 4 was still making the shader emit the code to load them,
causing page faults on simulation, and would also on HW if we didn't
always have a scratch page set.
The uses_inline_data parameter will be set from brw_compile_cs(), called
shortly after this point, so we don't need it here.
The subgroup_size is misleading, as we don't actually require that size
and the code that checks for it isn't even running for this shader.

As per the code comment added in this commit the nir produced from
glsl to nir doesn't always keep function declarations before the
code that calls them e.g. calls from within other function
implementations. The change in this commit works around this problem by
first cloning all function declarations in a first pass, then cloning
the implementations in a second pass once we have filled the remap
table.

KernelCI jobs have priority 44 and are very long-running jobs (and
there might be an issue with the KernelCI that makes it create hundreds
of jobs, @sergi is looking into that).
While bumping to 45+ would be enough to allow Mesa release staging
pipelines to run despite the KernelCI, during the CI meeting with @sergi
and @mupuf it was determined that the Mesa releases are an important
enough operation to warrant being a higher priority than user forks
pipelines, so priority 70 was picked (still under the 75 of Marge
pipelines).

Because dyn_start and dyn_end are indices into
nvk_root_descriptor_table->dynamic_buffers, we would need to offset
cbuf->dynamic_idx by
nvk_root_descriptor_table->set_dynamic_buffer_start[cbuf->desc_set]
in order to do those comparisons correctly.
We could do that, but it's simpler and no less precise to sinply
re-use the same comparison that we do in the other cases here.

The Early-Z optimization is disabled when there is a discard
instruction in the shader used in the draw call.
But if discard is the only reason to disable Early-Z, and at
draw call time the updates in the draw call are disabled we
can enable Early-Z using a shader variant.
If there are occlussion queries active we also need to disable
Early-z optimization.
So this patch enables Early-Z in this scenario.

Non-trivial collects (i.e., ones that will introduce moves because the
sources don't line-up with the destination) may cause source intervals
to get implicitly moved when they are inserted as children of the
destination interval. Since we don't support moving intervals in shared
RA, this may cause illegal register allocations. Prevent this by
creating a new top-level interval for the destination so that the source
intervals will be left alone.

It seems like this condition could be relaxed to cover cases like (note
