Arrow dataset builder to be able to load and stream Arrow datasets

This adds a Arrow dataset builder to be able to load and stream from already preprocessed Arrow files.
It's related to https://github.com/huggingface/datasets/issues/3035

_The documentation is not available anymore as the PR was closed or merged._

@lhoestq tips applied. Thanks for a review. :smile: It's a lot of fun to improve this project. 

Let's add some documentation in a subsequent PR :)

In particular @mariosasko  and I think it's important to note to users that local arrow data are copied to cache according to the way load_dataset works, but if they want they can use Dataset.from_file instead
