Provide a `process.setTitle()` function

What is the problem this feature will solve?

The process title can only be set via proccess.title. Problems with it:

• Setter APIs like it are weird and legacy, it's a side-effect that may look like a code smell
• Doesn't work with destructuring, setter is not triggered:

  import {title} from "node:process";
  title = "title";
  

What is the feature you are proposing to solve the problem?

import {setTitle} from "node:process";
setTitle("title");

What alternatives have you considered?

首先阅读现有的 process.title API 文档以及 issue 中描述的 node:process 入口点。将提议的 setTitle("title") 用法与当前 process.title 的行为进行比较，然后确定相关的实现和测试。新 API 已公开并完成文档编写，且有覆盖率证明它会设置进程标题，即视为完成。
