e934792169 introduced a workaround for
NVIDIA windows where NVIDIA drivers fail to allocate swapchain images
of minimized windows. The fix was to clamp it to 1,1. With this clamping
AMD driver seems to tell Blender that the created swapchain is suboptimal,
and needs to be recreated. This results in over and over creation of
swapchains as they are all considered sub-optimal.
This PR limits the clamping to NVIDIA drivers only.
