LibVirtGPU: Improve type safety of encode_command()

Browse source 
ObjectType is now passed as an enum instead of a plain number. The
underlying type for both ObjectType and VirGLCommand have been reduced
to u8 to make sure they fit in the encoded command. Command length is
verified to not overflow u16.
