Add <plug>(vimtex-env-toggle) for toggling environments

This implements a solution for #3072

This works for me as I expect :) Thanks a lot!

By the way, I personally remap the toggle commands because the default interferes with the t movement. I remap them to cx.... But I guess that might be too big a change from what people are already used to.

Regarding your question about other toggles, I can't really think of something I use so often. Maybe toggling different align environments? Not sure if it's standard enough to be in the plugin. I'll update if I think of something else.

Great, thanks for testing and for the feedback!

Ah, yes. I've found ts to be quite safe here, but some people use s for motion plugins as well. In any case, it's easy to remap so.

The point is that it is trivial to add toggles here. But then, it is also trivial to add more as a user. So I guess I could merge now and possibly add more default maps later.
