vpn: l2tp: T2264: migrate IPv6 prefix node to common CLI style

Combining multiple options into a single CLI node is considered bad practice.
IPv6 prefixes consited of the prefix itself and a mask send to the client in
one node only.

The following CLI parts have been migrated from

  client-ipv6-pool {
    delegate-prefix fc00:0:1::/48,64
    prefix 2001:db8::/64,64
  }

to

  client-ipv6-pool {
    delegate fc00:0:1::/48 {
      delegation-prefix 48
    }
    prefix 2001:db8::/48 {
      mask 64
    }
  }

Thus regular validation steps from the VyOS CLI can be used when a prefix is
configured.
