feat(library/tactic/exact): enforce goal type during elaboration when executing 'exact' tactic
...
Remark: this was the behavior of the 'sexact' tactic.
This commit also adds the 'rexact' (relaxed exact) tactic which does not
enforce the goal type.

We could not fix this problem before because we did not have the
[quasireducible] annotation.
Without this annotation, the fixed TC would loop in some HoTT files.
