feat: support generator core by xprofctl

[hyj1991]

• generator core by xprofctl
• auto generate core before abort if enable_fatal_error_coredump is true

close #169

---

演示死循环时动态生成 core 在 llnode 中的解析效果：

注意此处生成的是 ulimit -c 是 0，且生成的 core 文件为x-coredump-30500-20220430-0.core，即由 xprofiler 插件在 JS 工作线程死循环时获取。
