obs-filters: Test if NVAFX is supported on load

Browse Source 
Prevents situations where the redistributable is installed and OBS
enables the RTX denoiser but it is non-functional. Changes were tested
on systems with both supported / unsupported GPUs and it adds around
10-20ms to the load time in both cases.
