WifiConfigStoreData: Implement |createRawData|

Implement the method to serialize the WifiConfigStoreData instance to raw
bytes in XML format. This uses the all helper classes in XmlUtil to
serialize the data.

BUG: 29251019
TEST: Will add unit tests once the entire XML
serialization/deserialization is complete.
