Add a customizable NoMali GPU model and an example Mali T760 configuration. Unlike the normal NoMali model (NoMaliGpu), the NoMaliCustopmGpu model exposes all the important GPU ID registers to Python. This makes it possible to implement custom GPU configurations by without changing the underlying NoMali library.
