feat(apigatewayv2): add dualstack support to domain name

[laurelmay]

Reason for this change

This builds on #34054. Apparently for a domain name to have IPv4 and IPv6
support, the AWS::ApiGatewayV2::DomainName.DomainNameConfiguration also
needs to set IpAddressType. This is distinct from the settings on the
AWS::ApiGatewayV2::API itself.

Description of changes

This adds the ipAddressType property for DomainNameConfiguration.

Describe any new or updated permissions being added

N/A

Description of how you validated changes

Unit & Integration tests have been added. These are the first tests for DomainName
for HTTP APIs and leverage the tooling for custom domains in integ tests.
