refactor(library/tactic): refine interface between tactic and proof-term modes
...
Some constraints were being lost with the previous interface.
This is why we had a workaround in fintype.lean.
We can also remove some hacks we have used in the past.

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.

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.
