We've had many reported crashes on Windows where we suspect there is a corrupted OpenCL driver. The purpose here is to keep Blender generally usable in such cases. Now it always shows None / CUDA / OpenCL in the preferences, and only when selecting one will it reveal if there are any GPUs available. This should avoid crashes when opening the preferences or on startup. Differential Revision: https://developer.blender.org/D4265
