Variables not coming from a Record step should be available in Record Picker (#12708)

We want code and webhook variables available in Record Picker since
those can contains uuid.

This PR:
- update `WorkflowVariablesDropdownObjectItems.tsx` so it manages fields
properly
- factorise both dropdown into a commun hook
- update filterOutputSchema.ts so it does not filter fields that are not
FieldMetadata types
- set relation fields as record object in variable schema so those can
be selected as full record
