Outliner: Remove list of library overrides from general display modes

There is a dedicated Library Override display mode now, and showing
these elsewhere just adds noise and makes the code problematic to
maintain (since the same element hierarchy will be used in two entirely
different contexts). The corresponding filter settings are removed too.

Part of T95802.
