Splits IPAddressSpace's Local value into Local and Loopback, so 127.0.0.0/8 and ::1 are distinguishable from other private address space. This is prep work for the Local Network Access enforcement path (meta bug 250607), which needs to treat loopback more permissively than general local-network access.
