LibGfx+LibWeb: Move Gfx::ScaledFont caching from LibWeb into LibGfx

Browse source 
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.
