This is a follow-up to <a href="https://core.trac.wordpress.org/changeset/59461">[59461]</a>, which moved `get_plugin_data()` from `wp-admin/includes/plugin.php` to `wp-includes/functions.php` so it's available during the plugin loading process.
Related functions like `is_plugin_active()` are often used together and should therefore be moved as well, to improve backward compatibility for plugins which load `wp-admin/includes/plugin.php` only conditionally.
