Message:

Cron API: Run alternative wp-cron later, do not run on archived blogs.

Runs cron jobs later on sites using alternative cron, ie the ALTERNATE_WP_CRON constant is true, to more closely match when standard cron jobs are run. Jobs now run on the wp_loaded hook at priority 20. Prior to this change they would run on the init hook. This ensures custom post types and taxonomies are registered prior to the jobs running.

This change also prevents alternative wp-cron from running on archived or suspended multisite blogs as these are shut down prior to the wp_loaded hook from running.

Moves the existing functionality of wp_cron() in to a new private function _wp_cron().

Fixes #20537, #24160.
