LibTTF: Memory map TTF fonts instead of reading them into heap memory

Browse source 
All GUI applications currently load all TTF fonts on startup
(to populate the Gfx::FontDatabase. This could probably be smarter.)

Before this patch, everyone would open the files and read them into
heap-allocated storage. Now we simply mmap() them instead. :^)
