Add Mayhem integration

Mayhem is one of many fuzzing platforms, and we already have a few forks of the language that added Mayhem support, but they do not report any bugs they find here.

It would be better if we integrated Mayhem ourselves to get all the reports and address them efficiently.

该 issue 未指定任何文件、测试或入口点。首先定位项目现有的 fuzzing 集成，并查看所引用的语言 fork 如何添加 Mayhem 支持。当 Mayhem 直接集成到 ArkScript 中，并将发现的 bug 报告给本项目时，即视为完成。
