Kernel: Move all Graphics-related code into Devices/GPU directory
Like the HID, Audio and Storage subsystem, the Graphics subsystem (which handles GPUs technically) exposes unix device files (typically in /dev). To ensure consistency across the repository, move all related files to a new directory under Kernel/Devices called "GPU". Also remove the redundant "GPU" word from the VirtIO driver directory, and the word "Graphics" from GraphicsManagement.{h,cpp} filenames.
