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.

feat(library/tactic): 'exact' tactic report unsolved placeholders in nested expression
...
Actually, the elaborator is the one reporting the unassigned
placeholders. The 'exact' tactic just makes the request.
To implement this feature we had to extend the elaboration interface
expected by the tactic framework.

See new node.inj4 theorem, we need the extra power to be able to avoid type information at
exact (assume e₁ e₂, e₁)
