Before this change, we would only cache and reuse Gfx::ScaledFont instances for downloaded CSS fonts. By moving it into Gfx::VectorFont, we get caching for all vector fonts, including local system TTFs etc. This avoids a *lot* of style invalidations in LibWeb, since we now vend the same Gfx::Font pointer for the same font when used repeatedly.
