score: Add thread priority change handler
Since the thread current priority change and thread queue requeue is
performed in one critical section it is possible to simplify the thread
queue requeue procedure. Add a thread queue agnostic thread priority
change handler so that we are able to use alternative thread queue
implementations.
Update #2273.
