feat(route53): weighted routing

[badmintoncryer]

In this PR, I have implemented support for weighted routing.
By passing the weight and setIdentifier parameters when registering a record, it is possible to perform weighted routing among records that share the same name and type.

new route53.ARecord(this, `WeightedRecord${index}`, {
        zone: hostedZone,
        recordName: 'www',
        weight: 20, // added
        setIdentifier: 'uniqueId', // added
        target: route53.RecordTarget.fromIpAddresses('1.2.3.4'),
      });

Closes #26753.

Thank you for your comments.
I have made a modification to prevent the setting of setIdentifier for simple routing.

Love the review back and forth @lpizzinidev @badmintoncryer. Caught a few edge cases that are now synth-time checks :). This looks good to me :)
