[fix bug] logits's shape different from label's shape in preprocess_logits_for_metrics (#31447) * [fix BUG] pad labels before use it in preprocess_logits_for_metrics * a more readable fix labels can't use `gather` before pass to `preprocess_logits_for_metrics`, so must split into 2 if-block * add a comment * oh code quality check
