Make title as required on custom doctype layouts

When creating a custom document type, if I generate the layouts, the dc:title property is never set as mandatory.

This is a problem as Web UI enforces it client side.

When the configuration is deployed, I can't validate the creation form:

• if the title isn't filled with a value (there's no red star indicating it, and no error message)
• even if I calculate this value with an automation chain on the "About to create" event. In this case, the only workaround is to set a value in the script section, or to set a value with an automation chain on the "Empty document created" event.

=> Studio should provide consistent configuration with what Web UI provides to prevent confusing users

AC:

• For TPs 8.10+, in Designer
  • make title as required by default when generating a layout for a custom doctype in create / edit / import
  • make title required when d&d dc:title in edit mode
• Existing layouts should remain unaffected by the change
