CefFrame `evaluateJavascript` #450

Is your feature request related to a problem? Please describe. There is currently no way to execute some javascript and get the value back.

For example we wanna execute this script

(function() {
    const wantedA = document.getElementById("link");
    return wantedA.getAttribute("href");
})();

And get the String of the elements href back in Java.

Describe the solution you'd like This is already implemented in CefSharp like this:
