建议补充 istrue_with_null, istrue, isfalse 这三个操作符的功能描述

release-6.0.0-dmr#提升改进 TiDB 6.0 中有一个改进项是

支持下推 IS_TRUE、IS_FALSE、IS_TRUE_WITH_NULL 函数到 TiFlash #33047

但是官方文档中并没有对这三个操作符做出明显的、准确的定义，建议增加描述。

@windtalker 能为 istrue_with_null, istrue, isfalse 这三个操作符提供描述吗？谢谢

这三个操作符里面 istrue_with_null 实际上是我们内部的实现，istrue 和 isfalse 就是 MySQL 里面的 is 操作符。
