LibWeb: Wrap font metrics into a struct
Rather than passing an increasingly-unwieldy number of font parameters individually to every function that resolves lengths, let's wrap them up. This is frustratingly close to being `Gfx::FontPixelMetrics`, but bitmap fonts cause issues: We choose the closest font to what the CSS requests, but that might have a wildly different size than what the page expects, so we have to fudge the numbers. No behaviour changes.
