Add UsageSetting to IRadioNetwork

Add usage setting to IRadioNetwork(Response) and the associated
enum.

Expose the cellular usage setting to Android to be able to query and
set the modem to operate in a data-centric mode or a voice-centric
mode.
This facilitates "companion" subscriptions that might be data-only and
allows voice-centric devices to operate in data-centric mode on networks
that do not support voice service.

Bug: 210023167
Test: compilation

+// 2). this is a 'current' file. If you make a backwards compatible change to

+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.
