[ruby-core:99193] [Ruby master Feature#11689] Add methods allow us to get visibility from Method and UnboundMethod object.

Issue #11689 has been updated by jacobevelyn (Jacob Evelyn).


I'd also like to advocate for this. We're working on a gem that allows you to easily memoize a method while still preserving that method's visibility, and without `Method#visibility` we have to [awkwardly hack around it](https://github.com/panorama-ed/memo_wise/blob/master/lib/memo_wise.rb#L23):

```ruby
method_visibility = if private_method_defined?(method_name)
                      :private
                    elsif protected_method_defined?(method_name)
                      :protected
                    else
                      :public
                    end
```
