**Issue**
When creating a VPC you can not define the VPC name. The current way to set the name is using the `Tags` class

**VPC Example:**
```javascript
        const vpc = new ec2.Vpc(this, 'vpc-id', {
            maxAzs: 2,
            subnetConfiguration: [
                {
                    name: 'private-subnet-1',
                    subnetType: ec2.SubnetType.PRIVATE,
                    cidrMask: 24,
                },
                {
                    name: 'public-subnet-1',
                    subnetType: ec2.SubnetType.PUBLIC,
                    cidrMask: 24,
                },
            ]
        });

        cdk.Tags.of(vpc).add('Name', 'CustomVPCName');
```

**Proposal:**
```javascript
        const vpc = new ec2.Vpc(this, 'vpc-id', {
            maxAzs: 2,
            subnetConfiguration: [
                {
                    name: 'private-subnet-1',
                    subnetType: ec2.SubnetType.PRIVATE,
                    cidrMask: 24,
                },
                {
                    name: 'public-subnet-1',
                    subnetType: ec2.SubnetType.PUBLIC,
                    cidrMask: 24,
                    mapPublicIpOnLaunch: false, // or true
                },
            ],
            vpcName: 'CustomVPCName',
        });
```
