feat(frontends/lean): apply eta-reduction in postprocessing step

Perhaps, we should add an option to disable this new feature.
Remark: this commit makes commit 46d418a
redundant.
I'm keeping 46d418a
because we may retract this commit in the future.

renaming(hit): rename type_quotient to quotient, and quotient to set_quotient
...
This renaming is because type_quotient is a nonstandard name. I've had a discussion with Egbert
Rijke, Steve Awodey and Dan Licata, and the consensus for a better name was 'quotient'. I had to
make changes in src/kernel/hits/hits.cpp, I renamed g_type_quotient* by g_hit_quotient* (to avoid
name clash the standard library quotient, although I don't know whether that name clash would
matter).
