K2: Make filterOutOverridden helper satisfying its contracts

It's obviously expected that all overridden, not only direct ones
are considered

While it likely changes the behavior and some tests are expected to be
changed, original intention was to fix the behavior for other usages
(see later commits) and the part with tests are postponed with KT-58636
