feat(library/simplifier): we can "rewrite" with transitive relations
...
The simplifier does not really need the relation to be an equivalence.
Transitivity is the main required property (we need to chain rewrites
together).

feat(frontends/lean/parse_rewrite_tactic): change the semantics of rewrite[↑f] when f is recursive
...
After this commit it behaves like 'unfold f'.
That is, it will unfold f even if it fails to fold recursive
applications. Now, only 'esimp[f]' will not unfold f-applications when
it cannot fold the recursive applications.
This commit also closes #692 . It is part of a series of commits that
addresses this issue.
