LibGfx+WindowServer: Have WindowServer broadcast system font settings

Instead of everybody getting their system fonts from Gfx::FontDatabase
(where it's all hardcoded), they now get it from WindowServer.

These are then plumbed into the usual Gfx::FontDatabase places so that
the old default_font() and default_fixed_width_font() APIs keep working.
