[XR SDK] [URP] Custom Render Feature is not initialized when Stereo Rendering Mode is set to Single Pass Instanced
Reproduction steps:
1. Open the attached project ("1292097Repro.zip")
2. Open the "Grass Displacement RenderFeature Demo" scene
3. Make sure XR Plug-in Management->Oculus is enabled
4. Set Oculus Stereo Rendering Mode to Single Pass Instanced
5. Enter play mode
Expected result: Grass is fully rendered
Actual result: Grass is cut off (partially rendered)
Reproducible with: URP 7.5.1, 8.2.0, 11.0.0 (2019.4.16f1, 2020.1.17f1, 2020.2.1f1, 2021.1.0a10)

Resolution Note:
In the repro project, user script creates the m_GrassDisplacementFX based on the camera descriptor. The m_GrassDisplacementFX later binds to shader as Texture2D.
In XR single pass mode, the camera target descriptor's dimension is texture2DArray. This is the divergent behavior between XR and non-XR. Because of this, m_GrassDisplacementFX is created as texture2DArray and this caused the binding operation to fail.
After modifying the custom code to create m_GrassDisplacementFX as texture2D, custom render feature works as expected.
