Merge #21477: test: Add test for CNetAddr::ToString IPv6 address formatting (RFC 5952)

732c7bddeb tests: Add test for CNetAddr::ToString IPv6 address formatting (RFC 5952) (practicalswift)

Pull request description:

  Test that `CNetAddr::ToString` formats IPv6 addresses with zero compression and canonicalisation as described in [RFC 5952 ("A Recommendation for IPv6 Address Text Representation")](https://tools.ietf.org/html/rfc5952).

  Solving #21466 will hopefully be trivial with the ability to check zero compression correctness against these tests.
