Fix Maps PIP issue: DeviceConfig permission denial

Problem:
Exception thrown when maps was in PIP mode.

Solution:
Use Binder to give permission to Settings reading device config
SEPARATE_VOLUME_NOTIFICATION.

Bug: 261809910
Test: Manual. (from bug report) Launch Maps and navigate to a place.
Minimize maps app. Open Settings. Should open normally and not crash.
