Repack 8x block_iq4_nl into block_iq4_nlx8 + add AVX implementation

  • Reuse the existing block_q4_0x8 GEMV/GEMM implementation (the logic is the same, just the lookup table for nibbles -> bytes is different)
  • Cleanup some UNUSED macros (not exhaustive)

TODOs:

  • Test the __AVX512F__ path after the refactoring
