Instanced Stereo Rendering causing a build to fail when packaging for Android

If the user goes to the project settings and enables "Instanced Stereo" rendering it will fail to package for Android.

1. Open the editor
2. Open project settings
3. Enable "Instanced Stereo"
   Project settings > Rendering > VR > Instanced Stereo
4. Set the project up to package for Android
5. Package for ETC2
6. Notice that the build fails

Expected: The project would package out if instanced stereo is meant to be used with Android, if not the tool tip would have some kind of warning
Result: The feature has no warning and fails to build
