Pass token to renderer methods ?

[kapouer]

Describe the feature
Currently renderer methods get arguments cooked by marked Renderer Parser, as in code(code, infostring, escaped).
On the other hand, extensions rendered methods get a token parameter with all its properties.
I request that all renderer methods get a token.

Why is this feature necessary?
For example this.renderer.list won't know if the list is loose.

Describe alternatives you've considered
I could have asked for this.renderer.list to get a (body, ordered, start, loose) signature.
But passing the token around systematically seems to be much simpler.

I would love this. It would make certain things so much easier. Unfortunately this would be a huge breaking change to most marked renderers. If we could do this in a way that would allow the tokens and deprecate the old way first I would be on board.

Ideas, in my order of preference:

1. "opt-in" with a legacyRenderer: true flag
2. this.renderer.token = token before each call (considering that renderers are sync functions)
3. add a extensions.renderer catch-all method

@UziTech Is this something we can add along with #2805 for the next major version?

Ya this would be nice
