[tests] add tests for NAT64 prefix advertisement (#7361)

Browse Source 
This commit adds tests for NAT64 prefix
advertisement. BORDER_ROUTING_NAT64 is set to 1 to enable the feature
in tests.

It also adjusted some util functions for prefixes and routes in
netdata.

Testing outbound connectivity to IPv4 hosts is not covered yet. It
will be added after we update OTBR.
