Publish dream state to OverviewProxyService.
This change pipes the current dream state to OverviewProxyService,
similar to how doze information is shared. A condition has been
added to monitor the dream state, and a callback relays this
information to the StatusBarStateController. A new CoreStartable
maintains the monitor for this interaction.
