[DLSS][XR][HDRP] DLSS creates anti-aliasing artifacts with Single Pass and Multi Pass Instancing
Reproduction steps:
1. Open the user's attached project "SinglePassDLSS.zip"
2. Connect Oculus 1/2
3. Enter Play Mode
4. Observe the jagged edges of the Sphere
Expected result: Enabling DLSS does not create anti-aliasing artifacts and the edges are smooth
Actual result: Enabling DLSS creates anti-aliasing artifacts and the edges are jagged (see attached Results.png)
Reproduces on: HDRP 12.0.0 (2021.2.0b12, 2022.1.0a9)
Could not test 2019.4.30f1, 2020.3.22f1, 2021.1.18f1 due to errors when downgrading the project
Notes:
-Disabling DLSS and also disabling AA will show fewer jagged edges. Enabling FXAA and disabling DLSS will also show fewer artifacts
-User mentioned that the issue reproduces also with Mock HMD
-DLSS is enabled in "Assets/HDRPDefaultResources/DefaultHDRPAsset.asset" at Maximum Quality

This issue is caused by "Camera Jitter" in XR HDRP settings being off. When off, the jitterx/y that is sent to DLSS is zeroed out causing jagged edges in the output.
There should be a warning to warn the user that DLSS won't work correctly if this setting is disabled.

Resolution Note:
The Camera Jitter setting was set to false in the HDRP asset under XR. Enabling this option fixes the anti-aliasing.
