Add a specialized agx_batch for compute commands (queued to the CDM instead of
the VDM for graphics). This uses a sentinel value for the width.

create_shader_state passes ownership of the NIR to the driver, so we need to
free it when we destroy the shader CSO later. Use ralloc to manage this in a
uniform way between graphics and compute. Strategy from Panfrost.

This adds the basic scaffolding for compute kernels. There's a bit of churn to
make sure we don't need to hang onto the kernel NIR, since it's never used for
anything else except looking up the shader stage.
The compute kernels aren't actually wired up here, but they do get compiled.

We can avoid reading both width and height when the texture is a cube map, and
we do so more simply by relying on CSE+DCE (Alyssa).

Implement custom border colours, as required by OpenGL's CLAMP_TO_BORDER and
Vulkan with customBorderColor. This uses an extended sampler descriptor, which
has space for the custom border values. The trouble is that the border must be
packed into an internal interchange format that depends on the original format
in a complex way. That said, we're not solving NP-complete problems here, and it
passes the tests (dEQP-GLES31.functional.texture.border_clamp.* and piglit
texwrap).

Vulkan spec 18.8. Primitives Generated Queries:
When a generated primitive query for a vertex stream is active,
the primitives-generated count is incremented every time a
primitive emitted to that stream reaches the transform feedback
stage, whether or not transform feedback is active.
We can see the order of stages in chapter 27 Fixed-Function
Vertex Post-Processing, which shows that the transform feedback
stage is before rasterization (and therefore culling).
Conclusion is that culled primitives should be included
in the primitives generated query.
This commit makes sure to emit the primitives generated query
code before culling and uses the input primitive count passed
to the current wave instead of the exec mask after culling.

Match iadd(x, #y). The format shift will get constant-folded away and, if y
is sufficiently small, the constant will be inlined by the AGX backend
optimizer. This gets rid of piles of 64-bit arithmetic from lowering UBOs. It
probably doesn't matter for perf since that's happening in preamble shaders but
it *is* noisy.

The offset is in vec4s, not words (unlike the component). This doesn't matter
right now since we get everything lowered (offset -> 0) but it will come up if
we implement clip distances natively (instead of lowering in FS).

These implement gl_ClipDistance in hardware, avoiding the fragment shader
lowering. Unfortunately, they can't be disabled on a per-plane basis and they
can't be interpolated, so using them for OpenGL would still require a bunch of
extra lowering steps. Still, we should document the hardware and the caveats.

This works around bugs in a LOT of applications, since fp16 texture coordinates
are almost never appropriate even though it's a valid implementation of the GLES

This speeds up glReadPixels. Instead of reading from the write-combined
framebuffer and converting colours on the CPU, this blits on the GPU to a
writeback staging resource with the colour conversion for free, and memcpies
from the writeback staging resource on the CPU.
In general, due to textures being write combined and tiled/compressed by default
by staging resources being linear writeback, blit-based texture transfer should
win out (you were going to blit anyway), particularly when format conversion is
involved

We only need 4 byte alignment, not 8 bytes. This isn't a big difference in
practice, but it probably reduces padding in some cases. More importantly, it
corrects our XML to match what the hardware actually does, which is great.
(There is exactly enough room for a 40-bit address with 4 byte alignment.)

Check the size explicitly, instead of just implicitly in the GenXML pack: it is
the responsibility of the caller to split up larger uploads. While this is
nominally more complicated, agx_usc_uniform is called in the draw hot path
