Revert "Remove `:disable_with` in favor of `'data-disable-with'` option from `submit_tag`, `button_tag` and `button_to` helpers."

`disable_with:` is much easier to type than `"data-disable-with" =>`,
and the fact it uses "data-disable-with" => is an implementation concern,
it should not affect the public API.

This reverts commit 683fc4db.
