gl_device: Force GLASM on NVIDIA drivers 495-496
GLSL shaders currently do not render correctly on the recent NVIDIA drivers. This adds a check that forces assembly shaders for these drivers since they seem unaffected and adds a warning informing of the decision. Developers can disable the check by enabling graphics debugging.
