Added support for NAT64 when configuring Router NAT

[matheusaleixo-cit]

Adds sourceSubnetworkIpRangesToNat64 and nat64Subnetwork fields to compute RouterNat, allowing the support for public Router NAT services with NAT64 enabled.

Also adds dns64Config field to dns Policy, allowing the configuration of DNS64 server policies, required when using NAT64.

Fixes: #22116

& remove google-beta from test configs- the implicit google provider will be the beta provider inside these tests. We only use the specific beta factory for example tests so the docs use the beta provider!
