Add three marcos for ready queue bitmap operation

When a task is enqueued into or dequeued from the ready queue, the
bitmap that indicates the ready queue state should be updated.

These three marcos can be used in mo_task_dequeue() and
mo_task_enqueue() APIs to improve readability and maintain
consistency.
