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(init/logic): eq.mpr and eq.mp can be use for type casting
...
So, they should be `def`. Otherwise code generation will fail.

feat(library/constructions,library/inductive_compiler): automatically generate dependent eliminator for inductive predicates
...
The dependent eliminator for an inductive predicate C is called C.drec
TODO: construct dcases_on and drec_on using C.drec
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.
