feat(route53): multivalue answer routing

[badmintoncryer]

Issue

Closes #28939.

Reason for this change

When configuring multi-value answer routing, it was always necessary to set it via the L1 method or use an escape hatch.

Description of changes

I added multiValueAnswering property to RecordSetProps.

    new route53.ARecord(this, 'MultiValueAnswerRouting', {
      zone: hostedZone,
      recordName: 'www',
      target: route53.RecordTarget.fromIpAddresses('1.2.3.4'),
      multiValueAnswer: true, // added
    });

Description of how you validated changes

I added unit test and integ test.
