Recommit r125950, which was reverted by r125958 due to link failures on win_aura bot.

Aura/Ash split: Move ScreenAura to aura::RootWindowScreen.

What is now aura::RootWindowScreen was tightly bundled with aura::RootWindow. Instead of moving it to ash::ScreenAsh, I renamed it aurea::RootWindowScreen because there's a bunch of unit tests that use RootWindow as if it were the desktop. Screen integration stuff has been moved out of RootWindow (and related observers) and into ash::Shell.
