[iOS]App crashes on the devices which do not support Metal when Auto Graphics API is set only to Metal
How to reproduce:
1. Open the attached UnityBug_OpenGLES2Removed.zip
2. Build for iOS and open the Xcode project
3. Modify the Info.plist file: remove "metal" from "Required device capabilities"
4. Deploy the Xcode project to the iOS device
Reproducible with: 2019.3.0a2, 2019.3.5f1
Reproducible with:
- iPad 4th generation (10.3.3)
Notes:
- Could not find another device which does not support metal
- OpenGLES was deprecated in 2019.3 so could not test with earlier versions
- OpenGLES is deprecated, but the app should still not crash. Looks like OpenGLES was removed and must be added manually
The workaround would be to add manually OpenGLES to Graphics API

Resolution Note:
Removing Metal from required device caps won't change the fact that GLES 2 is not included in the build settings. You need to add it manually in Gfx API list.
