deprecate `halt_callback_chains_on_return_false` instead of `halt_and_display_warning_on_return_false`

`halt_and_display_warning_on_return_false` is not a public API and
application is using `halt_callback_chains_on_return_false`.

https://github.com/rails/rails/blob/5-0-stable/railties/lib/rails/generators/rails/app/templates/config/initializers/new_framework_defaults.rb.tt#L29
https://github.com/rails/rails/blob/5-0-stable/activesupport/lib/active_support.rb#L86..L88
