[OpenXR][HDRP] Ray-traced colored shadows render differently in left and right eye in VR causing flickering when using Single Pass Instanced Render Mode

SRP XR

-

Steps to reproduce:
1. Open the attached Google Drive project
2. Connect Oculus Link
3. Enter Play mode with Quest link connected
4. Move the headset around and observe the shadows rendering on one eye and not the other

Expected results: Ray-traced colored shadows render the same in left and right eye in VR and not causing flickering when using Single Pass Instanced Render Mode
Actual results: Ray-traced colored shadows render differently in left and right eye in VR causing flickering when using Single Pass Instanced Render Mode

Reproducible on: OpenXR 1.4.2 - 1.5.3 (2022.1.22f1, 2022.2.0f1, 2023.1.0a21)
Unable to test on 2021.3.15f1 and 2020.3.42f1 due to project errors when downgrading

Reproducible with these devices:
VLNQA00415 - Oculus Quest 2 (Quest 2), CPU: Snapdragon XR2, GPU: Adreno 650, OS: 10

Notes:
-Only reproduces with Single Pass Instanced Render Mode
-Only reproduces with OpenXR, due to OculusXR not being supported with Direct3D12
-DXR support is enabled with a test game object that has a lit transparent material with custom transmittance color and a directional light with ray-traced colored shadows
