[Core] Fn.ConditionIf doesn't capitalise properties name.

[pivstone]

When we put the nested resource properties in the Fn.ConditionIf, the output template doesn't capitalise those fields name. For NodeJs, we can change the name to Capital one, but for Typescript, we can't do it. The type check force us to use lower case.

Reproduction Steps

Here is the demo code

const cdk = require('@aws-cdk/core');
const dynamodb = require('@aws-cdk/aws-dynamodb');
const YAML = require('yamljs');

class HelloCdkStack extends cdk.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    new dynamodb.CfnTable(this, 'items', {
      keySchema: [
        {
          attributeName: 'itemId',
          keyType: dynamodb.AttributeType.STRING,
        },
      ],
      tableName: 'items',
      provisionedThroughput: {
        readCapacityUnits: 10,
        writeCapacityUnits: 10,
      },
      globalSecondaryIndexes: [
        cdk.Fn.conditionIf(
          'HasGlobalSecondaryIndex1',
          {
            IndexName: cdk.Fn.ref('IndexName'),
            KeySchema: [
              {
                AttributeName: cdk.Fn.ref('HashKeyName'),
                KeyType: 'HASH',
              },
            ],
            Projection: {
              ProjectionType: 'ALL',
            },
            ProvisionedThroughput: {
              readCapacityUnits: cdk.Fn.ref('readCapacityUnits'),
              writeCapacityUnits: cdk.Fn.ref('writeCapacityUnits'),
            },
          },
          cdk.Aws.NO_VALUE
        ),
      ],
    });
  }
}

const stackName = 'stack';
const app = new cdk.App();
new HelloCdkStack(app, stackName);
app.synth();
const { template } = app.synth().getStackByName(stackName);
console.log(YAML.stringify(template, 20, 2));

The output:

Resources:
  items:
    Type: 'AWS::DynamoDB::Table'
    Properties:
      KeySchema:
        -
          AttributeName: itemId
          KeyType: S
      GlobalSecondaryIndexes:
        -
          'Fn::If':
            - HasGlobalSecondaryIndex1
            -
              IndexName:
                Ref: IndexName
              KeySchema:
                -
                  AttributeName:
                    Ref: HashKeyName
                  KeyType: HASH
              Projection:
                ProjectionType: ALL
              ProvisionedThroughput:
                readCapacityUnits:   // Here is problem
                  Ref: readCapacityUnits
                writeCapacityUnits:
                  Ref: writeCapacityUnits
            -
              Ref: 'AWS::NoValue'
      ProvisionedThroughput:
        ReadCapacityUnits: 10
        WriteCapacityUnits: 10
      TableName: items

What did you expect to happen?

Capitalise the parameter name in the ConditionIf

but for Typescript, we can't do it. The type check force us to use lower case.

You can always use as any to cast typechecks away.

Other than that, this is a duplicate of #8396
