[XR SDK] [URP] Occlusion culling is inoperative



Reproduction steps:
1. Open the attached project ("")
2. Make sure MockHMD is enabled (Project Settings->XR Plug-in Management)
3. Open "BugScene" scene

5. Open Scene window, set Occlusion Culling to Visualise and Enable Visibility lines
6. Observe the objects that shouldn't be rendered

    Thanks for working so quickly on this Unity Team! Is the 2020.2 version publicly available yet? (I just tried Unity 2020.2.6 & URP 10.3.2 and observed the same results as before).
