So we do what we actually state in the comment. Particularly, the load
operation only affects the first subpass that uses the attachment,
after that we always want to load, but we were only doing that for
attachments marked as CLEAR.
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6766>
Generally, we can do this when they render to the same collection of
attachments and we only need to emit a single RCL for them.
To implement this, we need to track the first subpass that is included
in the job and rewrite our loads and stores in the RCL to refer to that
subpass instead of the current subpass (which would be the last included
in the RCL).
When we merge jobs we also reuse the tile state/alloc BOs and we only
emit the binning setup once.
The environment variable V3DV_NO_MERGE_JOBS can be set to disable
job merging and have each subpass be in a separate job. This can be
useful for debugging issues spawning from incorrect subpass merges.

Binner flushes should be emitted naturally at the end of each draw,
if we are finishing a job and it doesn't have the binner flush, it
probably means that we have bogus emission code somewhere.

As we make progress towards more complex submissions we will need to split
our command buffers into smaller executable units (jobs) that we can
submit indepdently to the kernel. This will be required to implement
pipeline barriers, split subpasses that have depedencies on previous
subpasses, split render passes that use more than 4 render targets, etc.
For now we keep things simple and we only keep one job as current
recording target in the command buffer, and we generate a new one
with every subpass or with any commands we see outside of a render pass
(only vkCopyImageToBuffer for now). In the future we probably want to
optimize this by merging subpasses into the same job when possible,
etc.

For now we only support the TLB path, which limits us to copying
regions that start at offset (0,0). In the future, we will need to add
a fallback path that uses blitting to copy regions with an offset.

We will use this when we implement copying images to buffers using the
TLB, where we'll need to setup a framebuffer and tiling configuration
for the TLB store to the destination buffer.

Initial port of the equivalent v3d_write_uniforms, to be used by the
cmd_buffer when emitting the drawing packets.
Initially doesn't include all the quniform types, only those needed by
the initial basic vulkan tests.

Before that commit we were calling get_viewport_xform to get those
values twice (to emit scissor and viewport), and we found that we
would need that info even more times. So let's just compute that info
when setting the viewport, and reuse the values.

Add support for V3D_DEBUG=clif. Useful to compare clif_dumps from
vulkan small-programs and the equivalent opengl ones.
As we are here we expand clif_dump_packet wrapper to use
v3d42_clif_dump_packet if needed, as the vulkan driver would use that
packet version.

Values still doesn't take into account having vertex elements data,
but keeps some of that half-done code in comments. It would be better
to do that when we get an example using it.

Starting with Viewport/Scissor data from VkGraphicsPipelineCreateInfo.
Note that initially this can be somewhat counter-intuitive. What we
are really doing it is filling up the structs with the dynamic stuff
from the pipeline, when such is not defined as dynamic. This is what
anv/radv does, and basically means that we treat both in the same way,
so easier after that.

The basic to get the spirv built to nir, including calling some common
nir passes. Pending deep review if all those are needed or if we miss
some, but for that it would be better to be able to run existing
tests.
Enough to get assembly generated for simple tests.

We would need on OpenGL to update values for all the textures used. On
OpenGL that value can be always took from the context or the nir
shader, but there are cases on Vulkan that it is not the case, or
would force up to recompute it.
