Use LocalePicker fragment in framework.

We move basic logics in LocalePicker from Settings to framework,
so that the other components can use it.
See also I1364c4810a115958662ca5d6e6e7f29c0c9b2569 for more
information.

Currently new LocalePicker in this package inherits that
in framework. The name should be same to accept activity-alias
naturally.

Depends on I8a398b9b77601cf88ea8a3840b92dcf7441e6103
