Chosen library and settings are not attached if preRender is not called

I've confirmed this issue as stated in #2988400-12: Chosen library and settings are not attached if preRender is not called → .

In some situations, if Drupal's render pipeline does not know about an element that Chosen has a callback for (currently select, date combo, or select other), then the Chosen library and settings are not attached.

Some possible scenarios:
- An element is written directly into a twig file
- An element is loaded by external JS (via an embed)

Additionally if the Chosen JS library is loaded by a custom theme, this can result in cases where the JS is loaded but the settings are not passed to drupalSettings, so all select:visible elements have Chosen applied instead of the elements selected in the "Apply Chosen to the following elements" field.

Possible resolutions:

1. #2988400-12: Chosen library and settings are not attached if preRender is not called → - call chosen_attach_library directly where you need it in your theme, block, etc. (This could be added to the docs somewhere.) A brute force approach might look like this:

function my_theme_preprocess_html(&$variables) {
...
    chosen_attach_library($variables['page']);
...
}

2. Update the "Use chosen for admin pages and/or front end pages" field
- Change the existing options to read like "Include Chosen on every page that contains elements it can act on".
- Add a new option: "Include Chosen on every page (even if Drupal doesn't know about elements Chose can act on)"
