[iOS] MSAA setting of the Camera is ignored when MSAA is enabled in the Quality settings
Reproduction steps:
1. Open the attached project "MSAA.zip"
2. Build and Deploy the Scene "SampleScene" to an iOS device
3. Capture the GPU frame and inspect the type of textures (See attached screenshots MSAA_Enabled.png and MSAA_Enabled_Alternate.png to see what to look at)
Expected result: MSAA is disabled
Actual result: MSAA is enabled
Reproducible with: 2019.4.29f1, 2020.3.17f1, 2021.1.18f1, 2021.2.0b9, 2022.1.0a5
Reproduced with:

Resolution Note (2022.1.X):
In this case Quality Settings MSAA Setting controls the backbuffer sample count of the application and even if there is a single camera with MSAA disabled, it will still create multisampled backbuffer. Application assumes it's going to be used if it's enabled and recreating it would be pretty expensive. If there are multiple cameras in the scene, and one of them has MSAA for it disabled - all of the rendering done for that camera will be without MSAA.
So to sum it up - the final target will depend on the quality settings (at least on iOS)
