feat(appsync): support Input Types for code-first approach

[BryanPan342]

Support Input Types for code-first approach. Input Types are special types of Intermediate Types in CDK.

Desired GraphQL Input Type

input Review {
  stars: Int!
  commentary: String
}

The above GraphQL Input Type can be expressed in CDK as the following:

CDK Code

const review = new appsync.InputType('Review', {
  definition: {
    stars: GraphqlType.int({ isRequired: true }),
    commentary: GraphqlType.string(),
  },
}); 
api.addType(review);
