Add .faces(), .verts(),.all_verts(), and .grids() functions to nodes.
Don't change BMesh data access yet. More complex const correctness
makes that situation more difficult.

One comment on the naming, otherwise looks good to me.

I personally think unique_verts and all_verts is better than implying one or the other (e.g. unique_verts and verts or verts and all_verts), but I don't feel too strongly about this at the moment.

Since the vast majority of cases just use verts, and you should really know what you're doing if you use all_verts(), I thought giving that the "weirder" name that stood out was better. The BMesh node naming is similar with "verts" and "other verts". I think it's probably clearer to think of the "non-unique" vertices as separate conceptually, like "boundary vertices".

Yeah, I think that's a good argument, that all_verts is a rarer usecase and should stick out more
