Title: AS::Callbacks: deprecate rescuable option

`:rescuable` option of the `define_callbacks` has only one usage in ActionDispatch::Callbacks and it's possible to get the same behavior without using it.

That is why we don't need `:rescuable` option to exists. As the result - callbacks compilation gets even more simple.
