Refactor code server to use a single queue

Prior to this patch, the code server had two internal queues, one to track module loading and another to track on_load callbacks. This pull requests refactors the code to have a single queue, in order to fix bugs and improve maintainability. Closes erlang#7466. Closes erlang#8510.
