fix: correct VirtIO GPU command opcodes and enable virgl feature

Browse Source 
Align 2D command opcodes, response opcodes, and 3D command opcodes with\nthe Linux UAPI definitions in include/uapi/linux/virtio_gpu.h. Enable\nVIRTIO_GPU_F_VIRGL feature negotiation during device initialization to\nactivate the virgl 3D rendering path.
