libchromeos: Add generic DBus data serialization/deserialization

Provide generic methods to write arbitrary C++ data to D-Bus
message buffers and read it back. Implement generic conatainer
support such as std::vector, std::map, std::pair to support
D-Bus ARRAY, DICT, STRUCT data types. Also using chromeos::Any
as a D-Bus VARIANT type.

Added a bunch of unit tests for dbus_utils.
