chore(library/init/data/quot): use Sort instead of Type
...
Remark: The kernel was already using Sort. So, the limitation was
artificial. Moreover, it may seem unnecessary to have quotients of
proofs in a proof irrelevant system, but this is useful for proving
a more general funext lemma. This more general version is needed in
the new tested contributed by @digama0.

fix(library/init/meta/tactic): use zeta reduction by default in the abstract tactic
...
Abstracting let-exprs may produce type errors.
In the future we may consider another strategy for `abstract`.
First, we try to abstract the `let`, then if it fails, we expand.
Not sure if this is a good idea.

We need this recursor for implementing dependent elimination for
inductive predicates.
We don't need to define acc.drec and eq.drec in the standard library anymore.
