* vulkan: optimize IQ4_XS matmul kernels

Assisted-by: OpenAI Codex

* vulkan: address IQ4_XS review nits

- drop the dead LOAD_VEC_A != 8 branch in the IQ4_XS shmem load; iq4_xs is
  in lut_load_vec_a()'s "8" list, so that path is never generated
- disable MMVQ for IQ4_XS on Intel (27.3% tg regression on A770)
- remove a stray empty line in types.glsl
