[Enhancement]: Add support for Performance Insights and Enhanced monitoring to the aws_rds_cluster resource

[anacronxinetd]

Description

For AWS RDS Multi-AZ clusters, Performance Insights and Enhanced monitoring can only be enabled at the cluster level. Testing with the latest version of the AWS provider (5.50.0), the option to do so is currently not supported. However, it is for the following resource: https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/rds_cluster_instance

Affected Resource(s) and/or Data Source(s)

aws_rds_cluster - https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/rds_cluster

Potential Terraform Configuration

resource "aws_rds_cluster" "example" {
  cluster_identifier        = "example"
  availability_zones        = ["us-west-2a", "us-west-2b", "us-west-2c"]
  engine                    = "mysql"
  db_cluster_instance_class = "db.r6gd.xlarge"
  storage_type              = "io1"
  allocated_storage         = 100
  iops                      = 1000
  master_username           = "test"
  master_password           = "mustbeeightcharaters"
}

Does this still need triage? One issue has been added/fixed, but the other (enhanced monitoring) is still not available at the cluster level using terraform.
