Scripts within Assembly Defintions are missing when used by scenes in Asset Bundles and when the Project is built using IL2CPP
Reproduction steps:
1. Open users attached project
2. Press Tools > Build App
3. Open the built project in <Project folder>/Builds/Test
Expected result: No errors in the Player
Actual result: "The referenced script on this Behaviour is missing!" errors are thrown
Reproducible with: 2021.2.19f1, 2021.3.0f1, 2022.1.0b15, 2022.2.0a9
Could not test with: 2019.4.37f1 (could not downgrade the project), 2020.3.33f1 (ArgumentException: Unhandled ManagedStrippingLevel value of 4)
Notes:
-only reproducible with IL2CPP scripting backend
-on windows, you might need to rename <Project folder>/Builds/Test to <Project folder>/Builds/Test.exe

Resolution Note (2022.2.X):
On IL2CPP builds managed code stripping is enabled - https://docs.unity3d.com/Manual/ManagedCodeStripping.html - and is removing these scripts since they are in a package and nothing in the build is referencing them. To prevent this from happening please use the BuildPlayer overload that takes a BuildPlayerOptions object and set the assetBundleManifestPath to the path to your StreamingAssets.manifest file - https://docs.unity3d.com/ScriptReference/BuildPlayerOptions-assetBundleManifestPath.html. This ensure that all of the scripts referenced in the streaming assets are found.
