• wip

• ggml-hexagon: add vectorized dot product function for FP32 and FP16 accumulation

• ggml-hexagon: optimize dot product functions for FP16 and FP32 with new vectorized implementations

• wip

• ggml-hexagon: optimize hvx_vec_dump_f32_n and hvx_vec_reduce_sum_qf32x2 functions for improved performance

• ggml-hexagon: refactor dot product functions to use a common loading function for improved readability

• optimize vector dot product functions to use unified reduction for improved performance
