LibOverride: Add a dedicated view in the Outliner.

This is a minimal, information-only view currently, listing by default
all the override data-blocks, with their user-edited override
properties.

System-generated overrides (like the overrides of pointers to other
override data-blocks) can be shown through a filter option.

Finally, potential info or warning messages from (auto-)resync propcess
are also shown, as an icon + tooltip next to the affected items.

Part of D10855.
