feat: in conv tactic, use try with_reducibe rfl (#3763) 
The `conv` tactic tries to close “trivial” goals after itself. As of
now, it uses
`try rfl`, which means it can close goals that are only trivial after
reducing with
default transparency. This is suboptimal

* this can require a fair amount of unfolding, and possibly slow down
the proof
   a lot. And the user cannot even prevent it.
* it does not match what `rw` does, and a user might expect the two to
behave the
   same.

So this PR changes it to `with_reducible rfl`, matching `rw`’s behavior.

I considered `with_reducible eq_refl` to only solve trivial goals that
involve equality,
but not other relations (e.g. `Perm xs xs`), but a discussion on mathlib
pointed out
that it’s expected and desirable to solve more general reflexive goals:
