VideoBackend/OGL: Prefer KHR_subgroup over NV_shader_thread.

Browse Source 
While the NV extension is totally fine, the KHR extension should be able to support more hardware.

For NVIDIA, the hardware either supports both or neither, it just needs a driver from the last two years.
For AMD, the drivers from late 2022-12 seems to bring support for the KHR extension.
For Intel, the KHR is also supported for some years.
