aws_cloudfront_distribution: acm_certificate_arn and cloudfront_default_certificate(false) conflicts

[ghost]

This issue was originally opened by @only1vinay as hashicorp/terraform#20511. It was migrated here as a result of the provider split. The original body of the issue is below.

---

viewer_certificate {
acm_certificate_arn = "${var.acm_certificate_arn}"
cloudfront_default_certificate = "${length(var.acm_certificate_arn) > 0 ? false : true}"
minimum_protocol_version = "TLSv1.1_2016"
ssl_support_method = "sni-only"
}

This part used to work, i.e we can make cloudfront_default_certificate false and pass acm_certificate_arn.
But Its resulting in error: viewer_certificate.0.acm_certificate_arn": conflicts with viewer_certificate.0.cloudfront_default_certificate

This means I need to pass either one of those, Which doesn't make it modular.
