HarmonyOS Tabs选项卡组件是否有懒加载

目前tabs没有懒加载能力，可参考示例如下：

@Entry
@Component
struct Index3 {
  @State currentIndex: number = 0
  @State tabContentArr: boolean[] = [true, false, false, false]
  tabContents: string[] = ["首页", "推荐", "发现", "我的"]

  build() {
    Row() {
      Column() {
        Tabs({ barPosition: BarPosition.End }) {
          ForEach(this.tabContents, (item: string, index) => {
            TabContent() {
              if (this.currentIndex === index || this.tabContentArr[index]) {
                TabChild({ index: this.currentIndex })
              }
            }.tabBar(item)
          })
        }
        .onChange((index) => {
          this.currentIndex = index
          this.tabContentArr[index] = true
        })
      }
      .width('100%')
    }
    .height('100%')
  }
}


@Component
export struct TabChild {
  @Prop index: number = 0;

  build() {
    Column() {
      Text(this.index + '')
    }
  }
}
