fix: preserve arrow binder names and info at simp
...
We use the idiom `revert; simp; ...; intro` in a few places. Some of
the reverted hypotheses manifest themselves as arrows in the target.
Before this commit, `simp` would lose the binder names and info when
simplifying an arrow, and we would get inaccessible names when
reintroducing them.
