Flatten page structure - Customized to false while having components

[GlennRicaud]

Linked to https://github.com/enonic/xp/issues/6820 A lot of old content have customized to false while having a template reference and components. This makes no sense, and again seems to have been part of a bad refactoring happening in a previous version. I also do not see the need of this boolean since if I understand this correctly: If you have a descriptor/controller, you are customized.

I will add an additional upgrade after the work done in https://github.com/enonic/xp/issues/6820 to set customized to true if there is a descriptor key on the page.

This is why you get the "Customize page" when modifying Superhero app.

This is the current algo for Page Data migration.

• Get the controller key
• If there is no controller key and there is a template reference
  • If there are components
  • Take the controller key of the referenced template as controller key
  • Else set the template reference
• If there is a controller key
  • Set customized to true
  • Set the controller key as descriptor key
  • If there is a config set the config
• Else
  • Set customized to false
