Reproduction steps:
1. Open the attached project "OCIssue-2019.zip"
2. Build and Run on Android device
3. Select CPU Usage Profiler Module
4. Select Raw Hierarchy in Module details panel
3. In Module details panel observe CullScriptable time (go to PostLateUpdate.FinishFrameRendering > RenderPipelineManager.DoRenderLoop_Internal() > Inl_UniversalRendererTotal > Inl_RendererCameraStack > Inl_UniversalRenderPipeline.RenderSingleCamera)

Expected result: The average time of CullScriptable function is ~2.5 ms (values range from 1.6 ms to 4 ms, most of the time stays under 3 ms)
Actual result: The average time of CullScriptable function is ~3.5 ms (values range from 2.1 ms to 5 ms, rarely rises to 7ms, most of the time stays over 3 ms)

Reproducible with: 13.1.3 (2022.1.0b1), 13.1.4 (2022.1.0b3), 13.1.2 (2022.2.0a1, 2022.2.0a2)

VLNQA00316, Samsung Galaxy Note10 (SM-N970F), Android 9, CPU: Exynos 9 Series 9825, GPU: Mali-G76

Notes:
- In Unity 2022.2.0a1 CullScriptable time can go under 2 ms when launching the app but after ~30 seconds of running the app it rarely goes under 3 ms
