Instead of having abstracted opcodes, we target directly the HW format
at the NIR translation.
The payload description gives us the order of the payload sources (we
can use that for pretty printing) and we don't have to have a
complicated scheme in the logical send lowering for the ordering. All
we have to do is build the header if needed as well as the descriptors.

We start by assigning a backend opcode to all tex instructions, use
that to figure out if we have packed sources and apply the lowering
accordingly.

Centralize all the information in one place and also make the mapping
decision from nir_tex_instr -> HW opcode much earlier.
This will help knowning exactly what the payload looks like early in
the backend IR and when it needs to lowered to a smaller SIMD size due
to HW limits. It will also allow NIR lowering to know when to combine
parameters into a single packed component.
Finally, this also reduces the amount of LOAD_PAYLOAD we need to carry
in the backend IR, because we don't have to generate VEC()
LOAD_PAYLOAD() for coordinates etc... Those are useless if there is
any other parameter in the payload and we need need to add one more
LOAD_PAYLOAD() when doing the logical send lowering.

After a recent change, `piglit-traces.sh` automatically sets the caching
proxy, so update the docs to reflect this.
Also update the name of the variable from `FDO_HTTP_CACHE_URI` to
`LAVA_HTTP_CACHE_URI`.
Fixes: fa74e939bf ("ci/piglit: automatically use LAVA proxy")

This reverts commit a219308867.
It's failing most of the tests on Anv :
$ ./deqp-vk -n dEQP-VK.wsi.xlib.maintenance1.scaling.*
Test run totals:
Passed: 88/2422 (3.6%)
Failed: 576/2422 (23.8%)
Not supported: 1758/2422 (72.6%)
Warnings: 0/2422 (0.0%)
Waived: 0/2422 (0.0%)
The only passing tests seem to be with this pattern :
dEQP-VK.wsi.xlib.maintenance1.scaling.*.same_size_and_aspect

Mostly, this is just a code restructure. The two biggest changes are
that we now have one timeout for all query waits and that we wait for
all of them up-front instead of waiting per-query.

This also makes all the paths a bit more clear because we only ever
clflushopt on the clflusopt paths and only ever clflush on the clflush
paths. It's really not much more code or logic duplication.

The x86 implementation was shamelessly stolen from intel_mem.c and the
aarch64 implementaiton was based on the code in Turnip.
