feat(frontends/lean/elaborator): do not apply delayed_coercions on equation lhs
...
The variables in the equation lhs do not have type at preprocessing
time (i.e., their type is a metavariable). So, they may seem candidates
for delayed_coercions. If the coercions are injected, we will not be
able to pattern match. Thus, we disable coercions in this case.

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.
