gl_device: Force GLASM on NVIDIA drivers 495-496

Browse source 
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.
