Andreas Kling 39045bfde8 LibWeb: Add basic support for requestAnimationFrame()
We now support rAF, driven by GUI::DisplayLink callbacks. It's a bit
strange how we keep registering new callbacks over and over.
That's something we can definitely optimize.

This allows you to update animations/whatever without doing it more
often than the browser can display.
