Move //{ash => chromeos/ash}/services/device_sync [1/3]

This CL moves public/ to //ch/ash/services/device_sync.

ChromeOS components and services are meant to live in chromeos/,
separate from Ash shell code. Fix a previous migration that used the
wrong directory.

This CL is part of the ChromeOS source code directory migration:
