So far, we have been able to utilize the mutex::wait_lock for serializing the blocked_on state, but when we move to proxying across runqueues, we will need to add more state and a way to serialize changes to this state in contexts where we don't hold the mutex::wait_lock. So introduce the task::blocked_lock, which nests under the mutex::wait_lock in the locking order, and rework the locking to use it.
