[openid_connect 3.x] Support role mapping

Will need a rebase.

This is a major feature which was still somewhere on my roadmap to tackle. Thanks for your work Jeroen! Will try to test this next week.

Warning: Undefined array key "enabled" in Drupal\keycloak\Plugin\OpenIDConnectClient\Keycloak->applyRoleRules() (line 758 of /var/www/html/web/modules/contrib/keycloak/src/Plugin/OpenIDConnectClient/Keycloak.php)

Noticed the following in the logs which should be fixed as well.

The Add and Remove button on the role mappings is still breaking the AJAX callback with the following errors:

Warning: Trying to access array offset on value of type null in Drupal\keycloak\Plugin\OpenIDConnectClient\Keycloak->rulesAjaxCallback() (line 530 of /var/www/html/web/modules/contrib/keycloak/src/Plugin/OpenIDConnectClient/Keycloak.php)

Message	TypeError: Drupal\Core\Render\MainContent\AjaxRenderer::renderResponse(): Argument #1 ($main_content) must be of type array, null given, called in /var/www/html/web/core/lib/Drupal/Core/Form/FormAjaxResponseBuilder.php on line 89 in Drupal\Core\Render\MainContent\AjaxRenderer->renderResponse() (line 49 of /var/www/html/web/core/lib/Drupal/Core/Render/MainContent/AjaxRenderer.php)

One thing that could improved is an explanation what the "Pattern" field does. I had to look into the code to figure out that the group pattern needed to be without the slash in front of it. So not /groupname but groupname. I guess a few examples with more complex use cases could help.

I'll create a small follow up for that. I tested this and it works great!

Created follow up: 📌 Explain the groups pattern field + documentation Active
