Just show the setting level bubble on the default monitor, since ChromeOS only really supports one monitor right now anyway.

Code like this will end up living in aura_shell::Shell by the time we end up figuring out how to support multiple monitors.

For now, this removes a USE_AURA ifdef/NOTIMPLEMENTED() and some unnecessary complexity for cros.
