libchromeos: Move Any from Buffet to libchromeos.

Move the Any class from Buffet to libchromeos and
changed its namespace from buffet:: to chromeos::

Updated the rest of Buffet code to with the changes
to the class's namespace and header file location.

Also, now that move constructors are officially allowed by
Google C++ coding style for project with C++11 feature
support, added back the move constructor to Any as
per http://crbug.com/387902
