Steps to Reproduce

1. Package a project to iOS on Windows
2. UBT compiles a project and codesign it natively with the latest code signature format.
3. In the packaging stage, IPP resigns IPA and changes its code signature to the old format. (0x20200)
4. Run the IPA on iOS 14.2 and above then see the compatibility warning.
