Select full record in variable dropdown (#8851)

Output schema is now separated in two sections:
- object, that gather all informations on the selectable object
- fields, that display object fields in a record context, or simply the
available fields from the previous steps

The dropdown variable has now a new mode:
- if objectNameSingularToSelect is defined, it goes into an object mode.
Only objects of the right type will be shown
- if not set, it will use the already existing mode, to select a field

When an object is selected, it actually set the id of the object
