feat(library/class): mark instances as quasireducible by default
...
quasireducible are also known as lazyreducible.
There is a lot of work to be done.
We still need to revise blast, and add a normalizer for type class
instances. This commit worksaround that by eagerly unfolding
quasireducible.

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(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.

feat(library/tactic/exact_tactic): modify 'exact' tactic semantics, use higher-order unification
...
See new node.inj4 theorem, we need the extra power to be able to avoid type information at
exact (assume e₁ e₂, e₁)
