[TASK] Deprecate various functionality in legacy tree implementations

This patch deprecates all old-style tree views
that have been in use for over 15 years now without
larger refactoring.

As we now use the web-component-based tree in most
places, these class and properties can now
be deprecated, in order to phase out old logic.
