Faster ARM_NEON GEMM implementation for legacy quants (#546)
* iq2_kt and iq3_kt work with new int trellis
Much slower than the fp16 based trellis. I guess, Apple doesn't
have int8_t SIMD on the M2-Max GPU.
* q4_0
83.6 t/s -> 128.4 t/s. q4_0_r8 is at 123.5 t/s
* q5_0
74.2 t/s -> 128.5 t/s. q5_0_r4 is at 111.4 t/s.
* q6_0
74.2 t/s -> 128.8 t/s. q6_0_r4 is at 107.2 t/s.
* q8_0
84.5 -> 128.7 t/s. q8_0_r8 is at 131 t/s.
* iq4_nl
84.5 t/s -> 128.1 t/s. iq4_nl_r4 is at 120.4 t/s
* q4_1
74.4 -> 115.4 t/s. There is no repacked variant
* q5_1
64.2 t/s -> 114.9 t/s. There is no repacked variant.
