Once the Wake Lock Mojo interface is hosted by the Device Service and the only usage of //device/power_save_blocker is within the Wake Lock implementation, these two implementations should be consolidated into //services/device as the internal implementation of the Wake Lock Mojo interface. Concretely, both directories should move into //services/device/wake_lock, which should be made visible in GN only to //services/device.
