video_core/gpu: Make GPU's destructor virtual

Because of the recent separation of GPU functionality into sync/async
variants, we need to mark the destructor virtual to provide proper
destruction behavior, given we use the base class within the System
class.

Prior to this, it was undefined behavior whether or not the destructor
in the derived classes would ever execute.
