Fixes #31766. The permutation of `q_proj` and `k_proj` needs to consider both `num_attention_heads` and `num_key_value_heads`.

Thanks for your PR @PenutChen, we really appreciate it!

@SunMarc it'd be awesome if you can review this when you have a minute.

@SunMarc Thanks for the advice! I noticed that there is already a Q4 Llama3 test. This update will change the expected text. Should I just update the expected text?

The perplexity of Llama3 Q4 is 1713.8865 before the fix and 6.4626 after the fix. The model comes from NousResearch/Meta-Llama-3-8B-GGUF.

They still produce reasonable output if the sequence length is short. This might be because only the q_proj and k_proj weights are abnormal, and their weights are relatively low. Other weights are robust to a certain extent, which could be the cause. This is just my guess.

Thanks for the confirmation !
