Rename EnrollmentHandlerChromeOS to EnrollmentHandler

This CL removes 'ChromeOS' suffix from EnrollmentHandlerChromeOS
because the class is under ash/ directory and not an implementation
of a generic enrollment interface.

This CL is part of the Chrome OS source code directory migration:
https://docs.google.com/document/d/1g-98HpzA8XcoGBWUv1gQNr4rbnD5yfvbtYZyPDDbkaE.
