Add a Table display mode to relation field widgets (#20929)

## Context

Adds a new Table layout to the FIELD widget for to-many relation fields.
On a record page, a relation can now be displayed as a full record table
(the same component used for record indexes and dashboard table widgets)
scoped to the records related to the current record.
