[IL2CPP] [iOS] build fails with error for type System.Configuration.Configuration

IL2CPP

-

Reproduction steps:
1. Open customer's project from the drive link (cmd+f "usp=sharing")
2. Build for iOS

Expected result: the project builds successfully
Actual result: build fails with "System.Configuration.Configuration" error

Reproducible with: 2019.4.28f1, 2020.3.12f1, 2021.1.12f1, 2021.2.0b1
Could not test with 2018.4.36f1 (project breaks)

Does not reproduce with Mac Standalone build

Note: After upgrading the project from 2019.4 to higher streams the error expression will be different (no further information about what managed code was being converted is available), in the error check for "existing item was: `System.Void System.Configuration.Configuration...".

    Resolution Note (2022.1.X):

    Project contained copies of System.Web.dll and System.Web.Services.dll in the Assets/Plugins folder. Overriding system DLL's by including them in the assets directory is not supported and will cause unexpected build errors.
