chromeos: Move //ash/common files into //ash
//ash contains the "Aura Shell" system UI used by Chrome OS. For the
mustash servicification project we initially started moving files into
//ash/mus vs. //ash/aura vs. //ash/common. This allowed us to use DEPS
to ban aura includes. We now support aura on mus all the time, so we
don't need this directory structure.
