LibWeb: Implement CanvasRenderingContext2D.measureText
This requires an implementation of the "text preparation algorithm" as specified here: html.spec.whatwg.org/multipage/canvas.html#text-preparation-algorithm However, we're missing a lot of things such as the CanvasTextDrawingStyles interface, so most of the algorithm was not implemented. Additionally, we also are not able to use a LineBox like the algorithm suggests, because our layouting infra is not up to the task yet. The prepare_text function does nothing other than figuring out the width of the given text and return glyphs with offsets at the moment.
