VPC: Ignore route table routes managed by VPC Lattice

[ewbankkit]

Description

When an association is made between a VPC Lattice service network and a VPC,
additional IPv4 and IPv6 destinations are added to that VPC's route tables:

% aws ec2 describe-route-tables --route-table-ids rtb-b2012dc9
{
    "RouteTables": [
        {
            "Associations": [
                {
                    "Main": true,
                    "RouteTableAssociationId": "rtbassoc-6d565b10",
                    "RouteTableId": "rtb-b2012dc9",
                    "AssociationState": {
                        "State": "associated"
                    }
                }
            ],
            "PropagatingVgws": [],
            "RouteTableId": "rtb-b2012dc9",
            "Routes": [
                {
                    "DestinationCidrBlock": "172.31.0.0/16",
                    "GatewayId": "local",
                    "Origin": "CreateRouteTable",
                    "State": "active"
                },
                {
                    "DestinationCidrBlock": "0.0.0.0/0",
                    "GatewayId": "igw-6aae1a13",
                    "Origin": "CreateRoute",
                    "State": "active"
                },
                {
                    "DestinationCidrBlock": "169.254.171.0/24",
                    "GatewayId": "VpcLattice",
                    "Origin": "CreateRoute",
                    "State": "active"
                },
                {
                    "DestinationIpv6CidrBlock": "fd00:ec2:80::/64",
                    "GatewayId": "VpcLattice",
                    "Origin": "CreateRoute",
                    "State": "active"
                }
            ],
            "Tags": [],
            "VpcId": "vpc-35b2f14d",
            "OwnerId": "123456789012"
        }
    ]
}

Ignore these routes as they are not managed by Terraform.
