As a page editor, I want to be able to add a form container so I can create / embed forms on pages.

Design

Acceptance Criteria

1. A new form container fragment will be available under the "Forms components" section in the page editor (see LPS-151867)
2. The new form container has to include all capabilities of the regular container (common styles, suitable for saved compositions, hide from search, hide / show fragment).
3. When dragging and dropping the form container to the page, the side bar will show:
   1. For display page templates:
      1. the "source" field will show the item that was selected when creating the DPT as default option
      2. the user can also select "Other Content", and then a dropdown "Content type" with the list of available entities for it to be mapped to will be shown. In case the item type has subtypes, these will be displayed in a second dropdown selector "Content subtype".
   2. In content pages, the Content Type selector will display a list of all the available entities to be mapped.
      1. In case the item type has subtypes, these will be displayed un a second dropdown selector.
4. The user won't be allowed to add fragments to the form container if it's not mapped to any entity.
5. If the form container has been mapped to an entity and there are mapped fragments inside, when unmapping the container it is returned to the empty state.

Note: warnings will be tackled in other story (LPS-152107)
