Generate: add missing logits processors docs

[gante]

What does this PR do?

Some logits processor classes were missing on the docs. This PR corrects it by:
1 - Adding all missing logits processors to the docs
2 - Adding missing top-level imports (to stay consistent with previously existing logits processors)

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

I've confirmed that the previously missing docs are now properly rendered in the doc preview 👍

Would be cool if the different logits appear in the small summary to directly jump to one or another:

given that there are so many different ones WDYT?

Also I noticed that the logit_process.py is not doctested, might be because some of the examples use big models, but would be cool to support them.

@ArthurZucker re tests -- fully on board. If you're okay with it, I'd like to do it on a separate PR :) Ditto for the side bar on the left, it is in need of an update!

@ArthurZucker ready for a re-review!

To recap, the previously reviewed version:

• Added missing logits processor docs

This version also:

• Updates the left-handed TOC for this page (splits the classes by framework, so it's easier to navigate; I've decided against enumerating the logits processors in the docs since the list is quite big)
• Sorts the logits processors in the docs by alphabetical order
• Adds missing output classes to the output class docs section

In parallel, other concerns raised in the PR are being tackled in another places:

• Generate: logits processors are doctested and fix broken doctests #25692 Adds logits processors to the doctests
