Notably, this should detect whether an interface is "available" or not, which should prevent the failure is with dual SIM card setups. This is gated behind a field trial for now, to ensure this doesn't cause any regressions due to false negatives (interfaces that are usable but not listed as available by NWPathMonitor).
