SwaggerV3不支持AnyOf数据类型

[qixm-burnish]

What happens(发生了什么)?

SwaggerV3 JSON文档生成时，api.d.ts中的AnyOf类型字段会被直接生成any。具体对比如下：

另外还有以下两种特殊情况：
1、生成类型错误：
对于ValidationError的定义如下：

  "ValidationError": {
      "properties": {
          "loc": {
              "items": {
                  "anyOf": [
                      {
                          "type": "string"
                      },
                      {
                          "type": "integer"
                      }
                  ]
              },
              "type": "array",
              "title": "Location"
          },
          "msg": {
              "type": "string",
              "title": "Message"
          },
          "type": {
              "type": "string",
              "title": "Error Type"
          }
      },
      "type": "object",
      "required": [
          "loc",
          "msg",
          "type"
      ],
      "title": "ValidationError"
  }

生成的错误类型如下：

export class ValidationError {
  /** loc ---------------array类型错误 ----------- */
  loc: array

  /** msg */
  msg: string

  /** type */
  type: string
}

2、这种特殊结构也需要单独处理：

"vehicle_series_ids": {
  "anyOf": [
    {
      "items": {
        "type": "integer"
      },
      "type": "array"
    },
    {
      "type": "null"
    }
  ],
  "title": "Vehicle Series Ids",
  "description": "车系id列表, None时为全部"
},
