Jeff Bolz 8161641005 vulkan: add iq4_nl support back to FA (#24585)
* vulkan: add iq4_nl support back to FA

I was originally concerned about wasting shared memory on the LUT, but it's small
and unlikely to matter in practice.

Also support q1_0 for non-coopmat2.

Fixes #23681

* remove q1_0 FA support

Jeff Bolz e920c523e3 vulkan: Use native e2m1 and e4m3 conversions for mxfp4/nvfp4 (#25338)
This uses the new VK_EXT_shader_ocp_microscaling_types extension to do fp4 type
promotions, and also uses the float8 extension to do ue4m3 promotions for
nvfp4. It's reasonable to assume that an implementation that supports fp4 will
also support fp8, so we don't need to handle all possible combinations of
support.

Jeff Bolz 1a7718b4c5 vulkan: support non-contig unary/glu ops (#24215)
* vulkan: support non-contig unary/glu ops

Change unary/glu ops to pass in all strides and use fastdiv for the index
calculation. Put all unary ops in one file, similar to glu, to share the
code. codex went ahead and added expm1 without me asking, but I had to
make it do a real precision analysis rather than just making stuff up.

unary.comp initially couldn't use generic_unary_head because there wasn't
space for xielu's additional constants. Fixing this required packing the
fastdiv 'L' values.

Jeff Bolz 55ac0909e5 vulkan: don't hold the device mutex while compiling pipelines (#23641)
* vulkan: don't hold the device mutex while compiling pipelines

We need to hold a lock while we traverse all pipelines and lazily initialize
them, but we don't need to hold it while the pipeline is being compiled. And
it doesn't need to be the same lock as the device mutex. We call load_shaders
each time a pipeline is needed, so we only need to compile that one pipeline
(and, for example, don't want to end up compiling a pipeline that another
thread should be compiling).

Matt Corallo 19620004f5 vulkan: Block-load Q3_K/Q6_K block data and subtract on 32b ints (#23056)
Q2_K/Q3_K/Q6_K do much better when using MMVQ on Intel BMG even
though they're only 2-byte aligned, and Q3_K still wins on
NVIDIA as well.

mesa isn't all that great at coalescing back-to-back loads from
alternating arrays, so we force it instead. Further, we can do
subtraction directly on a full int32_t rather than an i8vec4
with bit twiddling because the high bit is always free to start.

On Intel BMG on mesa, the switch to MMVQ provides an immediate
~57% perf increase in tg128 for unsloth/Qwen3.5-9B-GGUF:Q3_K and
~78% perf increase in tg128 for unsloth/Qwen3.5-9B-GGUF:Q6_K.

The futher switch to block loads leads to a ~24% perf increase in
tg128 for unsloth/Qwen3.5-9B-GGUF:Q3_K and a ~48% perf increase in
tg128 for unsloth/Qwen3.5-9B-GGUF:Q6_K.

Finally, Xe2 wins on MMVQ even for small k, so we take the NVIDIA
override for K quants on Xe2 as well.
