Summary:
This PR:

- Replaces the `data_source` with `lengths`
- Adds a `shuffle` argument to decide whether to shuffle the samples in the buckets.
- Add `max_len` and `min_len` to filter out samples that are > max_len or < min_len.

Summary:
### Change list

* Split the documentation of prototypes
* Add a new API reference section dedicated for prototypes.
* Hide the signature of KenLMLexiconDecoder constructor. (cc carolineechen )
  * https://489516-90321822-gh.circle-artifacts.com/0/docs/prototype.ctc_decoder.html#torchaudio.prototype.ctc_decoder.KenLMLexiconDecoder
* Hide the signature of RNNT constructor. (cc hwangjeff )
  * https://489516-90321822-gh.circle-artifacts.com/0/docs/prototype.rnnt.html#torchaudio.prototype.RNNT
* Tweak CTC tutorial
  * Replace hyperlinks to API reference with backlinks
  * Add `progress=False` to download

### Follow-up

RNNT decoder and CTC decode returns their own `Hypothesis` classes. When I tried to add Hypothesis of CTC decode to the documentation, the build process complains that it's ambiguous.
I think the Hypothesis classes can be put inside of each decoder. (if TorchScript supports it) or make the name different, but in that case the interface of each Hypothesis has to be generic enough.

Summary:
This commit updates the documentation configuration so that if an API (function or class) is used in tutorials, then it automatically add the links to the tutorials.

It also adds `py:func:` so that it's easy to jump from tutorials to API reference.

Note: the use of `py:func:` is not required to be recognized by Shpinx-gallery.

* Refactor tutorial organization

* Merge tutorial subdirectoris under to examples/gallery/tutorials
* Do not use index.rst generated by Sphinx-gallery
* Instead use flat structure so that all the tutorials are listed in left menu
* Use `_assets` dir for artifacts of tutorials

It turned out that generated tutorials can embed the audio if the following conditions are met.
This commit changes how audio samples are shown in tutorials so that they become playable in doc.

1. There is only one `IPython.display.Audio` call in a cell
2. An object of `IPython.display.Audio` is the last object interpreter receives in the cell
3. Audio format is `wav`
   (`flac` can be embedded as well, but browsers (Chrome/Safari) won't play it)

Move the computation of `#classes -> #bits` to the constructor of WaveRNN and attach it to the instance, so that it can be reused elsewhere.
