Fix priority ceiling updates

Description

We must not clear the priority updates in _Thread_queue_Extract_locked() since this function is used by the priority ceiling surrender operations after the ceiling priority handover from the previous owner to the new owner. This is especially important in SMP configurations.

Move the _Thread_queue_Context_clear_priority_updates() invocation to the callers.
