Fix T71812: Outliner walk navigation not activating

Walk navigation used a separate flag to select the element. This is
because activation and mode toggling were connected until rB702e00f91088
cleaned up the selection logic.

Now walk navigation can activate objects and other elements without
changing modes. This also addresses renaming in the outliner which
did renaming from the active element, not the walk element.
