Add Wav2Vec2 HuggingFace support (#103009)
This is not actually enabled in the benchmark suite as you need
https://github.com/pytorch/pytorch/pull/103001 and also training
is broken per https://github.com/pytorch/pytorch/issues/101160
but might as well review this part first.
Contains https://github.com/pytorch/pytorch/pull/102979 but
I will probably rebase past that once it lands.
