This adds the skeleton of a header section which will only appear when the device has two or more active mobile subscriptions. Subsequent CL's will add the actual logic implementing it. Also this moves up the airplane mode toggle higher up on the page, and removes the proxy selector entry (which has been unconditionally disabled by the ProxyPreferenceController for a while). Bug: 116349402 Test: manual (this is mostly a layout change - subsequent changes will have actual logic to test for the subscriptions header) Change-Id: Iaee338d5c13e05d3c2d9d04872a94cf90e5da588
