Linus Groh 9f4ac38f08 LibWeb: Add basic support for script string argument to setTimeout() ...

Instead of passing a function it is also possible to pass a string,
which is then evaluated as a classic script.

This means we now support the following example from the "timer
initialization steps", step 16 - except that it runs the timers in
reverse order, so the `log` result is `"TWO ONE "`.

https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#timer-initialisation-steps

    var log = '';
    function logger(s) { log += s + ' '; }

    setTimeout({ toString: function () {
      setTimeout("logger('ONE')", 100);
      return "logger('TWO')";
    } }, 100);
