(CDK CLI): migrate doesn't produce correct IAM policies

[mbonig]

Describe the bug

When importing this template:
https://github.com/awslabs/aws-cloudformation-templates/blob/master/aws/solutions/LambdaStaticIP/lambda-static.cfn.yaml

The IAM role has bad casing on the policy:

    const lambdaRole = new iam.CfnRole(this, 'LambdaRole', {
      assumeRolePolicyDocument: {
        version: '2012-10-17',
        statement: [
          {
            effect: 'Allow',
            principal: {
              service: 'lambda.amazonaws.com',
            },
            action: 'sts:AssumeRole',
          },
        ],
      },
      managedPolicyArns: [
        'arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole',
      ],
      path: '/',
      policies: [
        {
          policyName: 'EC2Permissions',
          policyDocument: {
            version: '2012-10-17',
            statement: [
              {
                effect: 'Allow',
                action: 'ec2:DescribeNetworkInterfaces',
                resource: '*',
              },
              {
                effect: 'Allow',
                action: 'ec2:CreateNetworkInterface',
                resource: '*',
              },
              {
                effect: 'Allow',
                action: 'ec2:DeleteNetworkInterface',
                resource: '*',
              },
              {
                effect: 'Allow',
                action: 'ec2:DescribeInstances',
                resource: '*',
              },
              {
                effect: 'Allow',
                action: 'ec2:AttachNetworkInterface',
                resource: '*',
              },
            ],
          },
        },
      ],
    });

Expected Behavior

I expected the IAM policy documents to have the correct casing and be deployable.

Current Behavior

lowercase properties are incorrect for these IAM policy statements

Reproduction Steps

run cdk migrate on the linked template. Try to deploy, it will fail.
