Improve error message for inconsistencies in package.py (#21811)
* Improve error message for inconsistencies in package.py Sometimes directives refer to variants that do not exist. Make it such that: 1. The name of the variant 2. The name of the package which is supposed to have such variant 3. The name of the package making this assumption are all printed in the error message for easier debugging. * Add unit tests
