Reproduction steps:
1. Open the user's attached project and select Android as the build target
2. Check that Project Settings -> Player -> Managed Stripping Level -> Low
3. Build the project
4. Open the \\Temp\\StagingArea\\Il2Cpp\\Managed\\Unity.AdaptivePerformance.dll
5. Verify how the scalers are included in the *.dll.
6. Set the Managed Stripping Level to High or Medium in Project Settings -> Player -> Managed Stripping Level -> High
7. Build the project again
8. Repeat the 4th step
9. Verify how the scalers are stripped out from the *.dll.

Expected result: AdaptivePerformance scalers remain in Unity.AdaptivePerformance.dll
Actual result: AdaptivePerformance scalers are stripped out from Unity.AdaptivePerformance.dll

Reproducible with: 2.1.0 (2019.4.38f1), 2.2.3 (2019.4.38f1, 2020.3.33f1), 3.0.2 (2021.3.1f1), 4.0.0 (2022.1.0f1, 2022.2.0a11)

Notes: Reproducible with Android build target.
To check Unity.AdaptivePerformance.dll contents use JetBrains DotPeek Assembly Browser or similar software.
With: 2021.3.1f1, 2022.1.0f1, 2022.2.0a11 Unity.AdaptivePerformance.dll location is: "\\Library\\Bee\\Android\\Prj\\IL2CPP\\Il2CppBackup\\Managed\\Unity.AdaptivePerformance.dll"
