The new activity card design proposed for Moodle 4.3 differentiates badge
information from other HTML content (displayed using the afterlink feature).
This commit adds a new activitybadge class that can be extended by any
module to display any content in a badge near the activity name. These
are the main features:
- The badge content is always plain text (no HTML).
- The badge style can be set (by default is initialized with badge-none,
but it can be set by any module).
- An optional URL to redirect the user when the badge is clicked.
- An optional ID to add the element in case the module wants to add some
JS to the badge events.
- Optionally, any other extra HTML attributes to the badge element (for
example, data attributes).
