Add rules for whether a script works under ConstrainedLanguage mode

Summary of the new feature

Windows admins using Code Integrity may want to know if their scripts require full language mode or will work with constrained language mode. It would be helpful to have PSSA rule to let them know which parts of their scripts won't work under constrained language mode.

Addtionally, scripts running in a Code Integrity environment have some additional checks which may make sense to have as rules as well.

Issue 中没有指定实现文件或测试。先阅读链接的 ConstrainedLanguage mode 指南和 PSScriptAnalyzer 项目结构，然后确定哪些 language-mode 和 Code Integrity 检查属于范围之内，再识别相关规则入口点和测试。
