feat: new resource reference interfaces

[otaviomacedo]

For every L1, generate a new interface called ICfn[ResourceName] and make them implement this interface. For example:

export interface ICfnAlias extends constructs.IConstruct {
  /**
   * The Amazon Resource Name (ARN) of the alias.
   *
   * @cloudformationAttribute AliasArn
   */
  readonly attrAliasArn: string;
}


export class CfnAlias extends cdk.CfnResource implements cdk.IInspectable, ICfnAlias {
...
}

Each individual part of a composite attribute is exposed individually:

export interface ICfnDataCellsFilter extends constructs.IConstruct {
  /**
   * Catalog id string, not less than 1 or more than 255 bytes long, matching the [single-line string pattern](https://docs.aws.amazon.com/lake-formation/latest/dg/aws-lake-formation-api-aws-lake-formation-api-common.html) .
   * This property gets determined after the resource is created.
   *
   * @cloudformationAttribute Ref
   */
  readonly attrTableCatalogId: string;

  /**
   * UTF-8 string, not less than 1 or more than 255 bytes long, matching the [single-line string pattern](https://docs.aws.amazon.com/lake-formation/latest/dg/aws-lake-formation-api-aws-lake-formation-api-common.html) .
   * This property gets determined after the resource is created.
   *
   * @cloudformationAttribute Ref
   */
  readonly attrDatabaseName: string;

  /**
   * UTF-8 string, not less than 1 or more than 255 bytes long, matching the [single-line string pattern](https://docs.aws.amazon.com/lake-formation/latest/dg/aws-lake-formation-api-aws-lake-formation-api-common.html) .
   * This property gets determined after the resource is created.
   *
   * @cloudformationAttribute Ref
   */
  readonly attrTableName: string;

  /**
   * UTF-8 string, not less than 1 or more than 255 bytes long, matching the [single-line string pattern](https://docs.aws.amazon.com/lake-formation/latest/dg/aws-lake-formation-api-aws-lake-formation-api-common.html) .
   * This property gets determined after the resource is created.
   *
   * @cloudformationAttribute Ref
   */
  readonly attrName: string;
}

In a synthesized template, each of these attributes will be rendered as a "Fn::Select": [n, "Fn::Split": ["|", {"Ref": "ResourceName"}]], where n corresponds to the position of that particular identifier in the overall string.

Basically adapted from #28189.
