use npu_apply_rotary_pos_emb when head_size is 128 and is noex_style ### What this PR does / why we need it? Optimize rope by extracting index_select from layers into model, which can reduce (layer_num -1) * 2 Gather ops in each prefill/decode stage. ### Does this PR introduce _any_ user-facing change? NA ### How was this patch tested? NA --------- Signed-off-by: David9857 <985700846@qq.com>
