DB API: Pass columns_to_join to instance_get_active_by_window_joined

This makes the instance_get_active_by_window_joined database API
configurable for which columns should be joined from other tables,
similar to instance_get_all.

This lays the groundwork for the Instance object to pass expected_attrs
to the DB API for filtering which columns to load.
