The compositor IPC path needs variable-font axes to survive transport with the font data that owns them. Add LibGfx-local specializations for FontVariationSettings, compile the new implementation into LibGfx, and expose the stored settings from Font so later font serializers can read them without reaching into the class internals. This is preparatory work required to add IPC between the main and compositor threads.
