chromeos: Add external brightness control to chrome://flags.

Make --ash-enable-brightness-control settable via
chrome://flags to permit testing of DDC/CI-based brightness
adjustments of external displays in powerd.

Also add a bit of code to ensure that even if powerd
announces a brightness change via D-Bus, Chrome never
displays a bubble if there's no internal display connected.
