HarmonyOS 'Function.bind' is not supported (arkts-no-func-bind)的警告

不支持bind，在ArkTS中，this的语义仅限于传统的OOP风格，函数体中禁止使用this，不支持在函数中使用this。

替代方案： 使用() => {this.xxx()} 绑定this的作用域

https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/typescript-to-arkts-migration-guide-V5#不支持functionbind

请参考示例修改：component:():void=>{this.contentBuilder()}

支持文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/arkts-builderparam-V5#初始化builderparam装饰的方法
