[MS55.2] Move NetworkStateSnapshot into module folder

framework-connectivity need to see the aidl files when
compiling IConnectivityManager.aidl, and it can only
include the files by specifying aidl include_dirs.
Thus, move the file into the module since the one outside
of the module is going to be deleted soon.
