Used to register for memory pressure level changes. watcher: memory pressure Watcher channel that the Provider will use to send level change messages to the client.

The current memory pressure level is immediately sent to the watcher when this method is called.

It is recommended that the root job in a component tree register for changes, rather than having individual jobs further down the tree register individually. A low client count will help minimize system churn due to a large number of memory pressure messages in transit at the same time. Also, the more context a job has, the better equipped it will be to react to memory pressure by controlling the behavior of children jobs in its tree.
