Add better error message to HubertForCTC, Wav2Vec2ForCTC if labels are bigger than vocab size.

Motivation

Following this issue: huggingface/transformers#12264 it is clear that an error message should be thrown if any of the any of the labels are > self.config.vocab_size or else silent errors can sneak into the training script.

So w

Hi
when I do classification with the pretrained vggface2 model, how do I match a probability to a name? do you have a list of labels for the trained model?

Thanks

1.希望可以把底层的api文档再完善一些，比如encoder,decoder，以便于复现一些论文
2.希望可以维护一个pytorch和paddle的api对照一览表，尽量全一些
3.错误日志能否准确一些，有时候datalaoder出的一些错误信息不好定位
4.能否增加使用梯度累加特性，进一步提高batch size
