chromeos: Show onscreen bubble when brightness changes.

This adds a BrightnessLibrary class that registers to receive
notification of brightness changes from the libcros code
that I added in http://codereview.chromium.org/5640003/,
a BrightnessBubble class to control an onscreen indicator of
the current brightness level, and a BrightnessObserver class
that wires up the two.

This change depends on
http://codereview.chromium.org/5603012/, which pulls the
updated version of libcros into Chrome.
