quickjs: add repl + qjscalc (#251)

- Compile repl.js & qjscalc.js and include them in qjs.com zip
- Change quickjs-libc.c / js_os_poll to handle Windows console

This last change is needed because poll and select on Windows forbid
non-socket handles and Cosmopolitan Libc hasn't polyfilled that yet.
