Add helper methods on Visibility (#14898)

Fixes #14825

Edit: After feedback, these are the updated methods:

- `toggle_inherited_visible(&mut self)`
- Toggles between `Visibility::Inherited` and `Visibility::Visible`. If
the value is `Visibility::Hidden`, it remains unaffected.
- `toggle_inherited_hidden(&mut self)`
- Toggles between `Visibility::Inherited` and `Visibility::Hidden`. If
the value is `Visibility::Visible`, it remains unaffected.
- `toggle_visible_hidden(&mut self)`
- Toggles between `Visibility::Visible` and `Visibility::Hidden`. If the
value is `Visibility::Inherited`, it remains unaffected.
