chore(library/init/data/int/basic): use abstract when transfering in an instance declaration
...
@johoelzl I'm using `abstract` tactic because instances are
automatically marked as [reducible], and they will be unfolded when
solving unification constraints. This cannot be avoided since we need to
solve unification constraints such as
int.has_add =?= comm_ring.to_has_add int.comm_ring
The `abstract tac` tactic creates an auxiliary lemma to store the proof
generated by `tac`. If we use `print int.comm_ring` we can see that
the definition is much smaller. The proofs are irrelevant. So, this has
no drawbacks, and gives us a good performance boost.

feat(library/init/meta/transfer): add transfer and use for int
...
This commit introduces the transfer method. As application it is
used it to prove that the integers form a commutative ring.

refactor(library/init/algebra): new transport from multiplicative to additive

The motivation is to avoid the problems produced by the "declare as
structure and then tag as class idiom" described in the file ring.lean.
