Kernel/Graphics: Merge VirtIO GraphicsAdapter and VirtIO GPU code

Browse source 
A VirtIO graphics adapter is really the VirtIO GPU, so the virtualized
hardware has no distinction between both components so there's no
need to put such distinction in software.

We might need to split things in the future, but when we do so, we must
take proper care to ensure that the interface between the components
is correct and use the usual codebase patterns.
