Outliner: Add icon column to toggle if library overrides are editable

Adds a column to the right in the Library Overrides Hierarchies view
mode to toggle editability of library overrides.

Note that making a library override non-editable currently involves
clearing all overridden properties. This is an arguable design choice,
we should probably at least warn the user before doing this.

Part of T95802.
