[beta6] Replace PHP hooks by more themer-friendly solutions

Careful about this:

ui_suite_dsfr_preprocess_pattern_footer(array &$variables) > default value related to the current website state

Because service_title is missing from footer definition:

function ui_suite_dsfr_preprocess_pattern_footer(array &$variables) {
  if (empty($variables['service_title'])) {
    $variables['service_title'] = \Drupal::config('system.site')->get('name');
  }
}

Usual work (we did the same tasks for other UI Suite themes)

• Replace _ui_suite_dsfr_add_class by add_class filter > DONE in commit 889ccd6
• Use preview templates > DONE in commit 889ccd6
• Use menu setting type > TODO

Specific to DSFR:

• Replace _ui_suite_dsfr_add_elements_attributes by create_attribute() in templates > DONE in commit 889ccd6
• Replace _ui_suite_dsfr_add_link_class by add_class filter > TODO

Waiting for ✨ Add links setting type Needs review

We can resume work.

Done: https://git.drupalcode.org/project/ui_suite_dsfr/-/merge_requests/48/com...

It works perfectly, but I'm waiting for the little bug on the preview page to be fixed before merging: https://www.drupal.org/project/ui_patterns_settings/issues/3345071#comme... ✨ Add links setting type Needs review
