Is there any way to enable Origin Shield with `sst.StaticSite`?

Hey <@U02BSMB8SUF>, can u give this a try:
```import * as cf from "aws-cdk-lib/aws-cloudfront";

const site;

site = new StaticSite(this, "Site", {
  path: "path/to/src",
  cfDistribution: {
    defaultBehavior: {
      origin: Lazy.any({
        produce(context) {
          return new cfOrigins.S3Origin(site.s3Bucket, {
            originShieldRegion: "us-east-1",
          });
        }
      }),
      viewerProtocolPolicy: cloudfront.ViewerProtocolPolicy.REDIRECT_TO_HTTPS,
    },
  },
});```


It might be a bit jarring at first, but what we are doing here is overriding the `defaultBehavior` of the distribution.

The tricky thing here is that we need to access the `s3Bucket` created internally in the `StaticSite`. And `Lazy.any` allows us to do that.
