Add a way to use another property as a template for facets

When a shadow FK property is created or two properties should be mapped to the same column (like the concurrency token in table-sharing) the facets need to match. This includes, but is not limited to: column name, store type, value converter, value comparer, nullability, etc.

To make this relationship more robust we can introduce a way of configuring a property to take its facets defaults from a different property.
