We needed this proguard flag because
ThreadNetworkService#onLocalNetworkInfoChanged will otherwise be
stripped. We need to keep the method to ensure the border routing
feature works.

Initially we put the flag in thread/service/proguard.flags. However,
this seems not working on udc-mainline-prod branch. After moving it to
Connectivity/service/proguard.flags, it works as desired.

This CL selects the Thread country code from location country code.
If the location country code is not avaliable, the country code `WW`
will be selected as the default Thread country code.

This CL also adds Shell commands for developers to override the Thread
country code for testing.
