Move AccelerometerType from ui to chromeos
Move the accelerometer code from ui/accelerometer to chromeos/accelerometer/. This allows for the last dependency from chromeos/ to ui/ to be removed.
Create a new utility class in ui/chromeos for vector based accelerometer work.
Update code that uses the accelerometer.
TEST=All existing accelerometer tests. MaximizeModeControllerTest, ScreenOrientationTest, DisplayPreferencesTest
