Disabling Shadow Denoiser causes raytraced shadows from Rect Lights to disappear
1. Create a 4.26 project with Ray tracing On
2. Create empty scene
3. Add basic geometry
4. Add a Rect Light
5. Make sure the Cast Ray Tracing Shadows is Enabled on the Rect Light
6. Open console command and add r.Shadow.Denoiser 0
Result: no ray tracing shadows from Rect Light(s)
Expected: ray tracing shadows remain from Rect Light(s) with shadow denoiser turned off
