[webui] Add migrations for Kiwi Packages

We got the needed attributes found in:
  - https://doc.opensuse.org/projects/kiwi/schema-doc/
  - https://doc.opensuse.org/projects/kiwi/doc/#sec.description.packages

We also introduced the needed validations in the models.

Pair-programmed by @DavidKang and @Ana06.
