APT: Move the shared font loading and relocation functions to their own subdirectory services/apt/bcfnt.

Applications can request the kernel to allocate a piece of the linear heap for them when creating a shared memory object.
Shared memory areas are now properly mapped into the target processes when calling svcMapMemoryBlock.

Removed the APT Shared Font hack as it is no longer needed.

HLE/Applets: Use the correct size for the framebuffer SharedMemory in the swkbd and MiiSelector applets.

This has been entirely superseded by MicroProfile. The rest of the code
can go when a simpler frametime/FPS meter is added to the GUI.
