[XR][URP][Quest] Low frame rate in Oculus Quest build when MSAA is set to 2x, 4x or 8x
Reproduction steps:
1. Open the attached project "FramerateQuest.zip"
2. Make sure that MSAA is set to either 2x, 4x or 8x in the URP asset located in "Assets/New Universal Render Pipeline Asset.asset"
3. Build for Quest 1
4. Either enable OVR metrics through Oculus Developer Hub or open the Profiler and connect it to the headset
Expected result: No frame rate instability in Oculus Quest build when MSAA is set to 2x, 4x or 8x
Actual result: Low frame rate in Oculus Quest build when MSAA is set to 2x, 4x or 8x
Reproduces on: URP 12.1.6 - 14.0.0 (2021.2.15f1, 2022.1.0b11, 2022.2.0a8)
Does not reproduce on: URP 10.8.1 (2020.3.31f1)
Could not test on 2019.4.36f1 due to OpenXR not being available
Reproducible on these devices:

Resolution Note:
After Testing with the attached project we are not seeing any problems. Tested with OXR 1.3.1 which was the included version and 1.5.3 which is most recent until 1.6 lands.
Didn't see any instability and was able to hit 72 hz consistently. The user project in both cases is just an empty scene with one XRI Raycast interactor . Overall was not able to reproduce.
Utilized both FramerateQuest.zip and FrameRateTest2.zip
