[Occlusion culling] Performance spike in Culling when Camera is not rendering every frame



Reproduction steps:
1. Download and open the repro project form the attached link
2. Open and play the "CorridorDemo" scene (Assets\Scenes)
3. Check in the profiler, that ever 2 seconds, when FakeCamera calls to Render function, it shows a performance spike on Culling call

- When on "FakeCamera" Culling Mask is set only to "water" layer there aren't any spikes. Spikes are about from 5 ms to 18 ms.
- This culling spike problem relates to realtime reflection probes as well. Performance spikes are higher about 10 ms when realtime reflection probe (set to render all elements) is rendered faster than every 0.5 s.

    Look if you find them in an empty scene.
