Description

Annotations in @aws-cdk/assertions cannot has multiple messages by logicalId because Messages is following type:

export type Messages = {
  [logicalId: string]: SynthesisMessage;
}

But Annotations in @aws-cdk/core can add multiple massages (info, warning and error) to same node because messages is just metadata of Node.

I think it is better that Annotations in @aws-cdk/assertions also handle multiple messages by logicalId.

Use Case

If this feature was implemented, when the aspect add multiple annotations to same node as this comment, users can test it.

Proposed Solution

Modifing type of Messages is needed.

from:

export type Messages = {
  [logicalId: string]: SynthesisMessage;
}

to:

export type Messages = {
  [logicalId: string]: SynthesisMessage[];
}

To do that safely, first I think it is better to try to type section and other private modules with generics <T>.
