sched/tcb: add a reference count to the TCB to prevent it from being deleted.

To replace the large lock with smaller ones and reduce the large locks related to the TCB,
in many scenarios, we only need to ensure that the TCB won't be released
instead of locking, thus reducing the possibility of lock recursion.
