add ArrayObject into AST type

[UMRzcz-831]

Happen to notice, JSTT fail to compile duplicate enum.

However,it works fine when the enum property is direct property of an object

example data

{
  "type": "object",
  "properties": {
    "asDirectPropertyEnumType": {
      "type": "integer",
      "description": "duplicate enum",
      "enum": [
        1,
        2,
        3,
        5,
        1,
        2,
        6,
        10,
        1,
        1,
        2,
        1,
        2
      ]
    },
    "result": {
      "type": "object",
      "properties": {
        "total": {
          "type": "integer",
          "description": "total num"
        },
        "data": {
          "type": "array",
          "items": {
            "type": "object",
            "properties": {
              "enumType": {
                "type": "integer",
                "description": "duplicate enum",
                "enum": [
                  1,
                  2,
                  3,
                  5,
                  1,
                  2,
                  6,
                  10,
                  1,
                  1,
                  2,
                  1,
                  2
                ]
              },
              "objectType": {
                "type": "object",
                "properties": {
                  "minAmount": {
                    "type": "integer",
                    "description": "minimum amount"
                  },
                  "maxAmount": {
                    "type": "integer",
                    "description": "maximum amount"
                  }
                },
                "description": "Object Propertie of ArrayObjectItem",
                "additionalProperties": false
              },
              "env": {
                "type": "integer",
                "description": "env"
              },
              "version": {
                "type": "string",
                "description": "version"
              }
            },
            "additionalProperties": false
          },
          "description": "data set"
        }
      },
      "additionalProperties": false
    }
  },
  "$schema": "http://json-schema.org/draft-04/schema#",
  "additionalProperties": false
}

In that way,I found out data like Object[] get no optimization in ./src/optimizer.

So i separate the type ARRAYOBJECT from just ARRAY,make sure the inside ast get optimized.

As result
e2e test case
compiled into

export interface ArrayObject {␊
      result?: {␊
        /**␊
         * total num␊
         */␊
        total?: number;␊
        /**␊
         * data set␊
         */␊
        data?: {␊
          /**␊
           * duplicate enum␊
           */␊
          enumType?: 1 | 2 | 3 | 5 | 6 | 10;␊
          /**␊
           * Object Propertie of ArrayObjectItem␊
           */␊
          objectType?: {␊
            /**␊
             * minimum amount␊
             */␊
            minAmount?: number;␊
            /**␊
             * maximum amount␊
             */␊
            maxAmount?: number;␊
          };␊
          /**␊
           * env␊
           */␊
          env?: number;␊
          /**␊
           * version␊
           */␊
          version?: string;␊
        }[];␊
      };␊
    }␊
