score: Simplify thread wait state handling
Remove the THREAD_WAIT_STATE_READY_AGAIN and simply use the initial value to
indicate that a thread does not wait on something. Rename
THREAD_WAIT_FLAGS_INITIAL to THREAD_WAIT_STATE_READY. This change is necessary
so that _Thread_Continue() can be called for threads which never waited on
something (for example dormant threads).
Update #4546.
