AK: Implement 'concept-host-serializer' in URL spec

This implementation will allow us to fix serialization of IPv6
addresses not being surrounded by '[' and ']'.

Nothing is calling this function yet - this will come in the next
(larger) commit where the underlying host representation inside of
AK::URL is changed from DeprecatedString to URL::Host.
