Gutenberg for Term Description

[goaround]

As suggested here https://github.com/Automattic/blocks-everywhere/issues/20 I tried to add support for the term description.

It works, but it is still wip because I need your help:

1. (Done) As the term description is only in the backend, I would propose supporting all blocks, not just a limited set.
2. I think it would be helpful if Gutenberg uses the full page with. Currently, the edit form limited to max-width: 800px. I would propose to override it with 100%.
3. (Works now) In the past, I used https://github.com/sheabunge/visual-term-description-editor to have at least the classic editor for the term description. But if there is an old description, it breaks because it has to be converted to blocks first. This is disabled, but I don't know how to enable it again for the term description.
