Part of #269. Stacked on #353.

The review of the plone.restapi side changed a few names and one setting. The control panel follows.

plone.restapi changes it follows

• Add content type settings and CRUD services plone.restapi#2070: a type's number of items is content_count, not items_total, which is the batching name next to items.
• Add content type settings and CRUD services plone.restapi#2070: the visibility settings have in_navigation (the plone.displayed_types record). They keep default_page, but the control panel no longer shows it: Volto and Plone Aurora don't use default pages.
• Report the whole workflow chain of a content type (#2061) plone.restapi#2090: a type's workflow reports its whole chain, instead of only the first workflow's id.

@plone/controlpanels

• Settings tab: "Show in navigation" replaces "Can be used as a folder's default page". The capability and settings field defaultPage is now inNavigation.
• Workflow tab: when a type's chain has more than one workflow, it says which, and that changing the workflow replaces the whole chain. WorkflowAssignment has an optional chain for it.
• plone.restapi driver: reads content_count, in_navigation and workflow.chain.
• Translations: the new messages in all six languages, and the default page ones removed.

Tests

• controlpanels: 135 tests, including the chain in the driver and in the Workflow tab.
• Acceptance, against Report the whole workflow chain of a content type (#2061) plone.restapi#2090: 23 passed, 2 skipped. The visibility test now also turns on "Show in navigation" and checks it's saved.
